HSI: ssi_protocol: Mark expected switch fall-throughs
Mark switch cases where we are expecting to fall through. This patch fixes the following warning (Building: arm): drivers/hsi/clients/ssi_protocol.c: In function ‘ssip_set_rxstate’: drivers/hsi/clients/ssi_protocol.c:291:6: warning: this statement may fall through [-Wimplicit-fallthrough=] if (atomic_read(&ssi->tx_usecnt)) ^ drivers/hsi/clients/ssi_protocol.c:294:2: note: here case RECEIVING: ^~~~ drivers/hsi/clients/ssi_protocol.c: In function ‘ssip_keep_alive’: drivers/hsi/clients/ssi_protocol.c:466:7: warning: this statement may fall through [-Wimplicit-fallthrough=] if (atomic_read(&ssi->tx_usecnt) == 0) ^ drivers/hsi/clients/ssi_protocol.c:472:3: note: here case SEND_IDLE: ^~~~ Notice that, in this particular case, the code comment is modified in accordance with what GCC is expecting to find.
