With imx, gcc produces a false positive warning: drivers/staging/media/imx/imx-media-csi.c: In function 'csi_idmac_setup_channel': drivers/staging/media/imx/imx-media-csi.c:457:6: warning: this statement may fall through [-Wimplicit-fallthrough=] if (passthrough) { ^ drivers/staging/media/imx/imx-media-csi.c:464:2: note: here default: ^~~~~~~ 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. Regards, Ian
