Subject: ACPI processor: Use safe_halt() rather than halt() in acpi_idle_play_dead()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=54f70077768e9aba37d9c5030b43497b6d5084fb;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

ACPI processor: Use safe_halt() rather than halt() in acpi_idle_play_dead()

ACPI code is shared by arch/x86 and arch/ia64. ia64 doesn't provide a plain
"halt()" function.  Use safe_halt() instead.
