I am unsure what would be the right Fixes, perhaps we can avoid putting any? Same for all the other patches, the Fixes tag look wrong.

Source and destination pixel formats fields of context structure should not be used as storage when resetting the format. Use local variables instead and let hantro_set_fmt_out() and hantro_set_fmt_cap() set them correctly later.
