Subject: platform / x86 / PM: Fix unused function warnings for CONFIG_PM_SLEEP
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=3567a4e2c52ce2f6fe74fc85690335ec7c96608e;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

platform / x86 / PM: Fix unused function warnings for CONFIG_PM_SLEEP

According to compiler warnings, quite some suspend/resume functions
in platform x86 drivers are not used for CONFIG_PM_SLEEP unset, so
add #ifdefs to prevent them from being built in that case.
