We get a few warnings when building kernel with W=1:
drivers/gpu/drm/amd/amdgpu/cz_smc.c:51:5: warning: no previous prototype for 'cz_send_msg_to_smc_async' [-Wmissing-prototypes]
drivers/gpu/drm/amd/amdgpu/cz_smc.c:143:5: warning: no previous prototype for 'cz_write_smc_sram_dword' [-Wmissing-prototypes]
drivers/gpu/drm/amd/amdgpu/iceland_smc.c:124:6: warning: no previous prototype for 'iceland_start_smc' [-Wmissing-prototypes]
drivers/gpu/drm/amd/amdgpu/gfx_v8_0.c:3926:6: warning: no previous prototype for 'gfx_v8_0_rlc_stop' [-Wmissing-prototypes]
drivers/gpu/drm/amd/amdgpu/amdgpu_job.c:94:6: warning: no previous prototype for 'amdgpu_job_free_cb' [-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'.

Also, I just noticed cz_write_smc_sram_dword() and if I am not mistaken
they seems identical in both:
  drivers/gpu/drm/amd/powerplay/smumgr/cz_smumgr.c  and,
  drivers/gpu/drm/amd/amdgpu/cz_smc.c
with a personal preference to the powerplay version I suppose.

Similar story with cz_send_msg_to_smc_async() *I think* but the
powerplay one uses some insane macro chain that dispatches to some
function called smum_wait_for_register_unequal(), quite hard to follow..

Any way, that is out of scope of the patch here.

Kind Regards,
Edward.

in drivers/gpu/drm/amd/powerplay/smumgr/cz_smumgr.c and
drivers/gpu/drm/amd/amdgpu/cz_smc.c, there are two functions named
cz_write_smc_sram_dword, but these two functions only have the same name,
but in fact they are different functions, even their declarations is
different.
