In preparation to enabling -Wimplicit-fallthrough, mark switch
cases where we are expecting to fall through.
This patch fixes the following warning:
drivers/usb/musb/musb_host.c: In function ‘musb_advance_schedule’:
drivers/usb/musb/musb_host.c:374:7: warning: this statement may fall through [-Wimplicit-fallthrough=]
if (qh->mux == 1) {
^
drivers/usb/musb/musb_host.c:383:3: note: here
case USB_ENDPOINT_XFER_ISOC:
^~~~
Warning level 3 was used: -Wimplicit-fallthrough=3
Notice that, in this particular case, the code comment is modified
in accordance with what GCC is expecting to find.
This patch is part of the ongoing efforts to enable
-Wimplicit-fallthrough.
