Subject: media: ov5647: Implement enum_frame_size()
X-Git-Tag: v5.12-rc1~134^2~303
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=464090c0af3de6f3fe3a6329f524eadb6a8d9744;p=tomoyo%2Ftomoyo-test1.git

media: ov5647: Implement enum_frame_size()

Implement the .enum_frame_size subdev pad operation.

As the driver only supports one format and one resolution at the moment
the implementation is trivial.
