In preparation to enabling -Wimplicit-fallthrough, mark switch cases where we are expecting to fall through. This patch fixes the following warnings by adding a missing break and a fall-through annotation: drivers/nfc/st21nfca/dep.c: In function ‘st21nfca_tm_event_send_data’: drivers/nfc/st21nfca/dep.c:391:3: warning: this statement may fall through [-Wimplicit-fallthrough=] switch (cmd1) { ^~~~~~ drivers/nfc/st21nfca/dep.c:404:2: note: here default: ^~~~~~~ In file included from ./include/linux/kernel.h:15, from ./include/linux/skbuff.h:17, from ./include/net/nfc/hci.h:21, from drivers/nfc/st21nfca/dep.c:17: drivers/nfc/st21nfca/dep.c: In function ‘st21nfca_im_recv_dep_res_cb’: ./include/linux/printk.h:303:2: warning: this statement may fall through [-Wimplicit-fallthrough=] printk(KERN_ERR pr_fmt(fmt), ##__VA_ARGS__) ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ drivers/nfc/st21nfca/dep.c:622:4: note: in expansion of macro ‘pr_err’ pr_err("Received a ACK/NACK PDU\n"); ^~~~~~ drivers/nfc/st21nfca/dep.c:623:3: note: here case ST21NFCA_NFC_DEP_PFB_I_PDU: ^~~~ Warning level 3 was used: -Wimplicit-fallthrough=3 This patch is part of the ongoing efforts to enable -Wimplicit-fallthrough.
