[PATCH 3/4] drm/amdgpu: add amdgpu_pm_acpi_event_handler() declaration

Show all headers | View raw

We get 1 warning when building kernel with W=1:
drivers/gpu/drm/amd/amdgpu/amdgpu_pm.c:37:6: warning: no previous prototype for 'amdgpu_pm_acpi_event_handler' [-Wmissing-prototypes]

In fact, it need to declare it in a header files.

So this patch adds the declaration in
drivers/gpu/drm/amd/amdgpu/amdgpu.h.
