[PATCH] drm/amd/powerplay/smumgr: mark symbols static where possible

[PATCH] drm/amd/powerplay/smumgr: mark symbols static where possible

[Baoyou Xie]

We get a few warnings when building kernel with W=1:
drivers/gpu/drm/amd/amdgpu/../powerplay/smumgr/tonga_smumgr.c:146:5: warning: no previous prototype for 'tonga_program_jump_on_start' [-Wmissing-prototypes]
drivers/gpu/drm/amd/amdgpu/../powerplay/smumgr/fiji_smumgr.c:816:5: warning: no previous prototype for 'fiji_save_vft_table' [-Wmissing-prototypes]
drivers/gpu/drm/amd/amdgpu/../powerplay/smumgr/polaris10_smumgr.c:743:5: warning: no previous prototype for 'polaris10_avfs_event_mgr' [-Wmissing-prototypes]
drivers/gpu/drm/amd/amdgpu/../powerplay/smumgr/iceland_smumgr.c:167:5: warning: no previous prototype for 'iceland_program_jump_on_start' [-Wmissing-prototypes]
....

In fact, these functions are only used in the file in which they are
declared and don't need a declaration, but can be made static.
So this patch marks these functions with 'static'.

Hi Baoyou,

All your drm/amd patches seem fine to me, but again (as with the nouveau
driver patches before), I think it would make more sense to consolidate
them, and do a small number of patches such as

[PATCH 1/3] drm/amdgpu: add missing includes
[PATCH 2/3] drm/amdgpu: remove unused functions
[PATCH 3/3] drm/amdgpu: mark symbol static where possible

This is all one big driver, and I see no value in splitting it up
per file within the driver.

Thanks to your patch. But powerplay part is refactored recently below, some
functions are already updated. So you might need rebase them. :-)

No it isn't. The different parts are developed by different teams at 
AMD, so the splitting them up is rather welcome here.

So please keep your style as it is, at least for the amdgpu driver.
