It would be useful to mark instances of v4l2_subdev_state structures as
const when code needs to access them read-only. This isn't currently
possible, as the v4l2_subdev_state_get_*() accessor functions take a
non-const pointer to the state.
Use _Generic() to provide two different versions of the accessors, for
const and non-const states respectively. The former returns a const
pointer to the requested format, rectangle or interval, implementing
const-correctness. The latter returns a non-const pointer, preserving
the current behaviour for drivers.

media: subdev: Support single-stream case in v4l2_subdev_enable/disable_streams()
At the moment the v4l2_subdev_enable/disable_streams() functions call
fallback helpers to handle the case where the subdev only implements
.s_stream(), and the main function handles the case where the subdev
implements streams (V4L2_SUBDEV_FL_STREAMS, which implies
.enable/disable_streams()).
What is missing is support for subdevs which do not implement streams
support, but do implement .enable/disable_streams(). Example cases of
these subdevices are single-stream cameras, where using
.enable/disable_streams() is not required but helps us remove the users
of the legacy .s_stream(), and subdevices with multiple source pads (but
single stream per pad), where .enable/disable_streams() allows the
subdevice to control the enable/disable state per pad.
The two single-streams cases (.s_stream() and .enable/disable_streams())
are very similar, and with small changes we can change the
v4l2_subdev_enable/disable_streams() functions to support all three
cases, without needing separate fallback functions.
A few potentially problematic details, though:
- For the single-streams cases we use sd->enabled_pads field, which
limits the number of pads for the subdevice to 64. For simplicity I
added the check for this limitation to the beginning of the function,
and it also applies to the streams case.
- The fallback functions only allowed the target pad to be a source pad.
It is not very clear to me why this check was needed, but it was not
needed in the streams case. However, I doubt the
v4l2_subdev_enable/disable_streams() code has ever been tested with
sink pads, so to be on the safe side, I added the same check
to the v4l2_subdev_enable/disable_streams() functions.

v4l2_subdev_enable/disable_streams_fallback() supports falling back to
.s_stream() for subdevs with a single source pad. It also tracks the
enabled streams for that one pad in the sd->enabled_streams field.
Tracking the enabled streams with sd->enabled_streams does not make
sense, as with .s_stream() there can only be a single stream per pad.
Thus, as the v4l2_subdev_enable/disable_streams_fallback() only supports
a single source pad, all we really need is a boolean which tells whether
streaming has been enabled on this pad or not.
However, as we only need a true/false state for a pad (instead of
tracking which streams have been enabled for a pad), we can easily
extend the fallback mechanism to support multiple source pads as we only
need to keep track of which pads have been enabled.
Change the sd->enabled_streams field to sd->enabled_pads, which is a
64-bit bitmask tracking the enabled source pads. With this change we can
remove the restriction that
v4l2_subdev_enable/disable_streams_fallback() only supports a single
source pad.

media: i2c: imx258: Make image geometry meet sensor requirements
The output image is defined as being 4208x3118 pixels in size.
Y_ADD_STA register was set to 0, and Y_ADD_END to 3118, giving
3119 lines total.
The datasheet lists a requirement for Y_ADD_STA to be a multiple
of a power of 2 depending on binning/scaling mode (2 for full pixel,
4 for x2-bin/scale, 8 for (x2-bin)+(x2-subsample) or x4-bin, or 16
for (x4-bin)+(x2-subsample)).
(Y_ADD_END – Y_ADD_STA + 1) also has to be a similar power of 2.
The current configuration for the full res modes breaks that second
requirement, and we can't increase Y_ADD_STA to 1 to retain exactly
the same field of view as that then breaks the first requirement.
For the binned modes, they are worse off as 3118 is not a multiple of
4.
Increase the main mode to 4208x3120 so that it is the same FOV as the
binned modes, with Y_ADD_STA at 0.
Fix Y_ADD_STA and Y_ADD_END for the binned modes so that they meet the
sensor requirements.
This does change the Bayer order as the default configuration is for
H&V flips to be enabled, so readout is from Y_STA_END to Y_ADD_STA,
and this patch has changed Y_STA_END.

The 'shutter' value is given to IMX412_REG_EXPOSURE_CIT however, the above
algorithm will result in the value given to IMX412_REG_EXPOSURE_CIT
decreasing as the requested exposure value from user-space goes up.
e.g.
[ 2255.713989] imx412 20-001a: Received exp 1608, analog gain 0
[ 2255.714002] imx412 20-001a: Set exp 1608, analog gain 0, shutter 1938, lpfr 3546
[ 2256.302770] imx412 20-001a: Received exp 2586, analog gain 100
[ 2256.302800] imx412 20-001a: Set exp 2586, analog gain 100, shutter 960, lpfr 3546
[ 2256.753755] imx412 20-001a: Received exp 3524, analog gain 110
[ 2256.753772] imx412 20-001a: Set exp 3524, analog gain 110, shutter 22, lpfr 3546
This behaviour results in the image having less exposure as the requested
exposure value from user-space increases.
Other sensor drivers such as ov5675, imx218, hid556 and others take the
requested exposure value and use the value directly.
Take the example of the above cited sensor drivers and directly apply the
requested exposure value from user-space. The 'lpfr' variable still
functions as before but the 'shutter' variable can be dispensed with as a
result.
Once done a similar run of the test application requesting higher exposure
looks like this, with 'exp' written directly to the sensor.
[ 133.207884] imx412 20-001a: Received exp 1608, analog gain 0
[ 133.207899] imx412 20-001a: Set exp 1608, analog gain 0, lpfr 3546
[ 133.905309] imx412 20-001a: Received exp 2844, analog gain 100
[ 133.905344] imx412 20-001a: Set exp 2844, analog gain 100, lpfr 3546
[ 134.241705] imx412 20-001a: Received exp 3524, analog gain 110
[ 134.241775] imx412 20-001a: Set exp 3524, analog gain 110, lpfr 3546
The result is then setting the sensor exposure to lower values results in
darker, less exposure images and vice versa with higher exposure values.

Looking into the codes, there is a loop in dvb_usb_read_remote_control(),
that is in rc_core_dvb_usb_remote_init() create a work that will call
dvb_usb_read_remote_control(), and this work will reschedule itself at
'rc_interval' intervals to recursively call dvb_usb_read_remote_control(),
see following code snippet:
dvb_usb_read_remote_control() {
...
err = d->props.rc.core.rc_query(d);
if (err)
err(...) // Did not return even if query failed
schedule_delayed_work(&d->rc_query_work,
msecs_to_jiffies(rc_interval));
}
When the infinite log printing occurs, the query callback
'd->props.rc.core.rc_query' is cxusb_rc_query(). And the log is due to
the failure of finding a valid 'generic_bulk_ctrl_endpoint'
in usb_bulk_msg(), see following code snippet:
By analyzing the corresponding USB descriptor, it shows that the
bNumEndpoints is 0 in its interface descriptor, but
the 'generic_bulk_ctrl_endpoint' is 1, that means user don't configure
a valid endpoint for 'generic_bulk_ctrl_endpoint', therefore this
'invalid' USB device should be rejected before it calls into
dvb_usb_read_remote_control().
To fix it, we need to add endpoint check for 'generic_bulk_ctrl_endpoint'.
And as Sean suggested, the same check and clear halts should be done for
'generic_bulk_ctrl_endpoint_response'. So introduce
dvb_usb_check_bulk_endpoint() to do it for both of them.

cifs: Fix missing set of remote_i_size
Occasionally, the generic/001 xfstest will fail indicating corruption in
one of the copy chains when run on cifs against a server that supports
FSCTL_DUPLICATE_EXTENTS_TO_FILE (eg. Samba with a share on btrfs). The
problem is that the remote_i_size value isn't updated by cifs_setsize()
when called by smb2_duplicate_extents(), but i_size *is*.
This may cause cifs_remap_file_range() to then skip the bit after calling
->duplicate_extents() that sets sizes.
Fix this by calling netfs_resize_file() in smb2_duplicate_extents() before
calling cifs_setsize() to set i_size.
This means we don't then need to call netfs_resize_file() upon return from
->duplicate_extents(), but we also fix the test to compare against the pre-dup
inode size.
[Note that this goes back before the addition of remote_i_size with the
netfs_inode struct. It should probably have been setting cifsi->server_eof
previously.]
