Subject: media: ov5640: Remove frame rate check from find_mode() Author: Jacopo Mondi <[email protected]> Date: Fri May 13 15:14:06 2022 +0100 The current implementation of ov5640_find_mode() fails if the frame rate programmed with s_frame_interval doesn't match the maximum frame rate for the current mode. This causes issues when moving from one mode with higher FPS to another one which only supports a lower FPS range with tools like media-ctl. It also forces users that do not use s_frame_interval(), but rather configure blankings explicitly, to adjust the programmed FPS range to avoid failures. For this reason, remove the FPS check from ov5640_find_mode() and only perform it at s_frame_interval() time.
