NFC: pn533: mark expected switch fall-throughs
In preparation to enabling -Wimplicit-fallthrough, mark switch
cases where we are expecting to fall through.
This patch fixes the following warnings:
drivers/nfc/pn533/pn533.c: In function ‘pn533_transceive’:
drivers/nfc/pn533/pn533.c:2142:6: warning: this statement may fall through [-Wimplicit-fallthrough=]
if (dev->tgt_active_prot == NFC_PROTO_FELICA) {
^
drivers/nfc/pn533/pn533.c:2150:2: note: here
default:
^~~~~~~
drivers/nfc/pn533/pn533.c: In function ‘pn533_wq_mi_recv’:
drivers/nfc/pn533/pn533.c:2267:6: warning: this statement may fall through [-Wimplicit-fallthrough=]
if (dev->tgt_active_prot == NFC_PROTO_FELICA) {
^
drivers/nfc/pn533/pn533.c:2276:2: note: here
default:
^~~~~~~
Warning level 3 was used: -Wimplicit-fallthrough=3
This patch is part of the ongoing efforts to enable
-Wimplicit-fallthrough.
