Subject: [PATCH] cpufreq: s3c244x: add fallthrough comments for switch
Date: Mon, 27 Sep 2021 11:51:44 +0200 [thread overview]
Message-ID: <20210927095150.944127-1-arnd@kernel.org> (raw)
From: Arnd Bergmann <arnd@arndb.de>
Apparently nobody has so far caught this warning, I hit it in randconfig
build testing:
drivers/cpufreq/s3c2440-cpufreq.c: In function 's3c2440_cpufreq_setdivs':
drivers/cpufreq/s3c2440-cpufreq.c:175:10: error: this statement may fall through [-Werror=implicit-fallthrough=]
camdiv |= S3C2440_CAMDIVN_HCLK3_HALF;
^
drivers/cpufreq/s3c2440-cpufreq.c:176:2: note: here
case 3:
^~~~
drivers/cpufreq/s3c2440-cpufreq.c:181:10: error: this statement may fall through [-Werror=implicit-fallthrough=]
camdiv |= S3C2440_CAMDIVN_HCLK4_HALF;
^
drivers/cpufreq/s3c2440-cpufreq.c:182:2: note: here
case 4:
^~~~
Both look like the fallthrough is intentional, so add the new
"fallthrough;" keyword.
