usb: isp1760-hcd: Fix fall-through annotations
In preparation to enabling -Wimplicit-fallthrough, mark switch cases where we are expecting to fall through. This patch fixes the following warning: drivers/usb/isp1760/isp1760-hcd.c: In function ‘collect_qtds’: drivers/usb/isp1760/isp1760-hcd.c:788:6: warning: this statement may fall through [-Wimplicit-fallthrough=] mem_reads8(hcd->regs, qtd->payload_addr, ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ qtd->data_buffer, ~~~~~~~~~~~~~~~~~ qtd->actual_length); ~~~~~~~~~~~~~~~~~~~ drivers/usb/isp1760/isp1760-hcd.c:792:5: note: here case OUT_PID: ^~~~ Warning level 3 was used: -Wimplicit-fallthrough=3 Notice that, in this particular case, the code comments are 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. Silva <gustavo@embeddedor.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
