Subject: media: meson-ge2d: Access v4l2_fh from file
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=e732b1221dbdf8b54ab5c85f06012962001f2c48;p=users%2Fhch%2Fmisc.git

media: meson-ge2d: Access v4l2_fh from file

The v4l2_fh associated with an open file handle is now guaranteed
to be available in file->private_data, initialised by v4l2_fh_add().

Access the v4l2_fh, and from there the driver-specific structure,
from the file * in all ioctl handlers.
