[PATCH] gpu: amd/pm: mark symbols static where possible for smu11

2023-03-02 Thread Jeff Pang 
I get one warning when building kernel with -Werror=missing-prototypes :

drivers/gpu/drm/amd/amdgpu/../pm/swsmu/smu11/vangogh_ppt.c:1600:5:
error: no previous prototype for ‘vangogh_set_apu_thermal_limit’
[-Werror=missing-prototypes]
int vangogh_set_apu_thermal_limit(struct smu_context *smu, uint32_t limit)

In fact, this function don't need a declaration due to it's only used
in the file which they are.
So this patch marks the function with 'static'.

Thanks. But I think there was already a patch from Kun Liu to address this 
issue.
