Subject: [PATCH v2 06/22] media: rockchip: rga: remove redundant rga_frame
variables
Remove the redundant rga_frame variables width, height and color space.
The value of these variables is already contained in the pix member
of rga_frame. The code also keeps these values in sync. Therefore drop
them in favor of the existing pix member.
Signed-off-by: Sven Püschel <s.pueschel@...gutronix.de>
