cpufreq: s3c244x: add fallthrough comments for switch
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.
