That's because the regex it uses for fall trough is not
good enough. So, rearrange the fall through comment in a way
that gcc will recognize.

Adding a '-' to the fallthrough seems to meet the regex requirements at
level 3 of the warning. Eg...
/* fallthrough- for non-passthrough RGB565 (CSI-2 bus) */
Not sure if this is an improvement though.
