Subject: nvram: Drop the bkl from non-generic nvram_llseek()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=9e8ab74ddaa591575f599248080a1f0d917a56ee;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

nvram: Drop the bkl from non-generic nvram_llseek()

Drop the bkl from nvram_llseek() as it obviously protects nothing.
The file offset is safe in essence.
