Subject: hw_random: Remove BKL from core
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=a09ba31a54dbc9a548c4ff90619e4c7128a4282e;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

hw_random: Remove BKL from core

hw_random core is completely serialized with rng_mutex. No need for
the cycle_kernel_lock() magic.
