Subject: media: ov2680: Fix ov2680_enum_frame_interval() Author: Hans de Goede <[email protected]> Date: Thu Aug 3 11:33:33 2023 +0200 Fix and simplify ov2680_enum_frame_interval(), the index is not an index into ov2680_mode_data[], so using OV2680_MODE_MAX is wrong. Instead it is an index indexing the different framerates for the resolution specified in fie->width, fie->height. Note validating fie->which is not necessary this is already done by the v4l2-core.
