It is because ctx is no more used in this function.

Keep in mind, we have to make sure the hantro_ctx state remains unchanged when the operation fails. The entire hantro_v4l2.c format negotiation is done without this case in mind (controls can change the format enumeration), so this new case needs some refactoring.
I will change hantro_reset_raw_fmt() prototype to: int hantro_reset_raw_fmt(struct hantro_ctx *ctx); so I will be able to return the result of hantro_set_fmt_out() or hantro_set_fmt_cap() when setting the control. Does that sound correct for you ? Regards, Benjamin
I also think we need v4l2-compliance tests for it. Thanks!
