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.
