Subject: platform/x86: surface3-wmi: Shut up unused-function warning
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=44e6861646748a21b55725adc0780342f4440066;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

platform/x86: surface3-wmi: Shut up unused-function warning

The newly added driver guards its "resume" callback with an
warning in some configurations:

drivers/platform/x86/surface3-wmi.c:248:12: error: 's3_wmi_resume' defined but not used [-Werror=unused-function]

Using a __maybe_unused annotation without an #ifdef avoids the mistake more
reliably.
