mtd: cfi_cmdset_0002: 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/mtd/chips/cfi_cmdset_0002.c: In function ‘get_chip’: drivers/mtd/chips/cfi_cmdset_0002.c:870:6: warning: this statement may fall through [-Wimplicit-fallthrough=] if (mode == FL_READY && chip->oldstate == FL_READY) ^ drivers/mtd/chips/cfi_cmdset_0002.c:873:2: note: here default: ^~~~~~~ drivers/mtd/chips/cfi_cmdset_0002.c: In function ‘cfi_amdstd_sync’: drivers/mtd/chips/cfi_cmdset_0002.c:2745:16: warning: this statement may fall through [-Wimplicit-fallthrough=] chip->state = FL_SYNCING; ~~~~~~~~~~~~^~~~~~~~~~~~ drivers/mtd/chips/cfi_cmdset_0002.c:2750:3: note: here case FL_SYNCING: ^~~~ Warning level 3 was used: -Wimplicit-fallthrough=3 This patch is part of the ongoing efforts to enabling -Wimplicit-fallthrough.
