drm/mipi_dbi: Fix off-by-one bugs in mipi_dbi_blank()
When configuring the frame memory window, the last column and row
numbers are written to the column resp. page address registers. These
numbers are thus one less than the actual window width resp. height.
While this is handled correctly in mipi_dbi_fb_dirty() since commit 03ceb1c8dfd1e293 ("drm/tinydrm: Fix setting of the column/page end

to subtract one when calculating the most significant bytes of the

udmabuf: fix dma-buf cpu access
I'm just going to put Chia's review comment here since it sums
the issue rather nicely:
"(1) Semantically, a dma-buf is in DMA domain. CPU access from the
importer must be surrounded by {begin,end}_cpu_access. This gives the
exporter a chance to move the buffer to the CPU domain temporarily.
(2) When the exporter itself has other means to do CPU access, it is
only reasonable for the exporter to move the buffer to the CPU domain
before access, and to the DMA domain after access. The exporter can
potentially reuse {begin,end}_cpu_access for that purpose.
Because of (1), udmabuf does need to implement the
{begin,end}_cpu_access hooks. But "begin" should mean
dma_sync_sg_for_cpu and "end" should mean dma_sync_sg_for_device.
Because of (2), if userspace wants to continuing accessing through the
memfd mapping, it should call udmabuf's {begin,end}_cpu_access to
avoid cache issues."

drm/print: introduce new struct drm_device based logging macros
Add new struct drm_device based logging macros modeled after the core
kernel device based logging macros. These would be preferred over the
drm printk and struct device based macros in drm code, where possible.
We have existing drm specific struct device based logging functions, but
they are too verbose to use for two main reasons:
* The names are unnecessarily long, for example DRM_DEV_DEBUG_KMS().
* The use of struct device over struct drm_device is too generic for
most users, leading to an extra dereference.
For example:
DRM_DEV_DEBUG_KMS(drm->dev, "Hello, world\n");
vs.
drm_dbg_kms(drm, "Hello, world\n");
It's a matter of taste, but the SHOUTING UPPERCASE has been argued to be
less readable than lowercase.
Some names are changed from old DRM names to be based on the core kernel
logging functions. For example, NOTE -> notice, ERROR -> err, DEBUG ->
dbg.
Due to the conflation of DRM_DEBUG and DRM_DEBUG_DRIVER macro use
(DRM_DEBUG is used widely in drivers though it's supposed to be a core
debugging category), they are named as drm_dbg_core and drm_dbg,
respectively.
The drm_err and _once/_ratelimited variants no longer include the
function name in order to be able to use the core device based logging
macros. Arguably this is not a significant change; error messages should
not be so common to be only distinguishable by the function name.
Ratelimited debug logging macros are to be added later.
