Subject: [PATCH] mtd: cfi_util: mark expected switch fall-throughs
Date: Fri, 8 Feb 2019 12:02:02 -0600 [thread overview]
Message-ID: <20190208180202.GA16603@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_util.c: In function ‘cfi_build_cmd’:
drivers/mtd/chips/cfi_util.c:110:10: warning: this statement may fall through [-Wimplicit-fallthrough=]
onecmd |= (onecmd << (chip_mode * 32));
~~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
drivers/mtd/chips/cfi_util.c:112:2: note: here
case 4:
^~~~
drivers/mtd/chips/cfi_util.c:113:10: warning: this statement may fall through [-Wimplicit-fallthrough=]
onecmd |= (onecmd << (chip_mode * 16));
~~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
drivers/mtd/chips/cfi_util.c:114:2: note: here
case 2:
^~~~
drivers/mtd/chips/cfi_util.c: In function ‘cfi_merge_status’:
drivers/mtd/chips/cfi_util.c:163:7: warning: this statement may fall through [-Wimplicit-fallthrough=]
res |= (onestat >> (chip_mode * 32));
~~~~^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
drivers/mtd/chips/cfi_util.c:165:2: note: here
case 4:
^~~~
drivers/mtd/chips/cfi_util.c:166:7: warning: this statement may fall through [-Wimplicit-fallthrough=]
res |= (onestat >> (chip_mode * 16));
~~~~^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
drivers/mtd/chips/cfi_util.c:167:2: note: here
case 2:
^~~~
Warning level 3 was used: -Wimplicit-fallthrough=3
This patch is part of the ongoing efforts to enabling
-Wimplicit-fallthrough.
