Subject: ACPI / PAD: power_saving_thread() is not freezable
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=21657471688508ced523b3bf0a763d73d546ad1a;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

ACPI / PAD: power_saving_thread() is not freezable

power_saving_thread() calls try_to_freeze(), but the thread doesn't mark
itself freezable through set_freezable(), so the try_to_freeze()
call is useless.
