Subject: cpufreq: exynos5440: Fix potential NULL pointer dereference
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=116decb7e48b46a8c171bd47f377fa527067f788;p=linux-beck.git

cpufreq: exynos5440: Fix potential NULL pointer dereference

If 'dvfs_info' is NULL (due to devm_kzalloc failure) the failure
error message would try to dereference it. Use 'pdev' instead.
