Subject: [PATCH] mtd: cfi_cmdset_0002: Mark expected switch fall-throughs
Date: Fri, 8 Feb 2019 12:06:15 -0600 [thread overview]
Message-ID: <20190208180615.GA24601@embeddedor> (raw)
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.
