Subject: ARM: restart: add restart hook to machine_desc record
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=a528721da08a793e0cec6ef6281d404eddd6e27b;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

ARM: restart: add restart hook to machine_desc record

Add a restart hook to the machine_desc record so we don't have to
populate all platforms with init_early methods to initialize the
arm_pm_restart function pointer.
