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.
