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. Signed-off-by: Gustavo A. R.
