Subject: media: nxp: mx2: Access v4l2_fh from file
X-Git-Tag: v6.18-rc1~133^2~390
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=cdc569967504fc1c9db7a1302e6d9ef4e4422553;p=thirdparty%2Fkernel%2Flinux.git

media: nxp: mx2: 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.
