Subject: ACPI / hotplug / PCI: Sanitize acpiphp_get_(latch)|(adapter)_status()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=1ad3790ac7cfac699993a3f2e189a69a82f8fe4d;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

ACPI / hotplug / PCI: Sanitize acpiphp_get_(latch)|(adapter)_status()

There is no need for a temporary variable and all the tricks with
ternary operators in acpiphp_get_(latch)|(adapter)_status(). Change
those functions to be a bit more straightforward.
