Subject: [PATCH] APM: Remove redundant call to set_cpus_allowed
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=910de55c6653d76f90380c80f0b7a395f12019e3;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

[PATCH] APM: Remove redundant call to set_cpus_allowed

machine_power_off now always switches to the boot cpu so there
is no reason for APM to also do that.
