From 012602c560b43a6de4c82a463bb4f282d50c38b4 Mon Sep 17 00:00:00 2001 From: Michael Tretter Date: Fri, 13 Oct 2023 13:00:29 +0200 Subject: media: rockchip: rga: use pixelformat to find format Use the pixelformat instead of the v4l2_format to find the rga_fmt. This avoids knowing the structure and type of v4l2_format in rga_fmt_find and simplifies the function. Also cleanup the users of the function. In try_fmt always return the found pixel format to make sure that the pixel format is always set. Thus, we can be sure that we will find the rga_fmt in s_fmt and can drop the check if a given format has been found.
