Subject: cpufreq: exynos: Initialize return variable
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=229b21e2b75302d6d1b931031ae7d53e1a4d0830;p=linux-beck.git

cpufreq: exynos: Initialize return variable

'ret' is undefined when the function returns from the first
'if' condition. Without this patch we get the following warning:

drivers/cpufreq/exynos-cpufreq.c: In function 'exynos_target':
drivers/cpufreq/exynos-cpufreq.c:182:2: warning: 'ret' may be used uninitialized in this function [-Wuninitialized]
