Subject: media: rcar-vin: Centralize black listing of pixel formats
X-Git-Tag: v5.4-rc1~145^2~244
X-Git-Url: https://asedeno.scripts.mit.edu/gitweb/?a=commitdiff_plain;h=21a816e7ee5d4b217da14374af1c91eb725e665c;p=linux.git

media: rcar-vin: Centralize black listing of pixel formats

Instead of scattering black listing of pixel formats who are not
supported on particular platforms move it to a central location.
