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.
