Silva Date: Sun, 28 Jul 2019 18:51:38 -0500 Subject: i2c: s3c2410: Mark expected switch fall-through Mark switch cases where we are expecting to fall through. This patch fixes the following warning: drivers/i2c/busses/i2c-s3c2410.c: In function 'i2c_s3c_irq_nextbyte': drivers/i2c/busses/i2c-s3c2410.c:431:6: warning: this statement may fall through [-Wimplicit-fallthrough=] if (i2c->state == STATE_READ) ^ drivers/i2c/busses/i2c-s3c2410.c:439:2: note: here case STATE_WRITE: ^~~~ Notice that, in this particular case, the code comment is modified in accordance with what GCC is expecting to find.
