Subject: [PATCH 1/3] drm/amdgpu: mark gfx_v9_4_3_disable_gpa_mode() static

From: Arnd Bergmann <[email protected]>

This was left global by accident, the corresponding functions for other
hardware types are already static:

drivers/gpu/drm/amd/amdgpu/gfx_v9_4_3.c:1072:6: error: no previous prototype for function 'gfx_v9_4_3_disable_gpa_mode' [-Werror,-Wmissing-prototypes]

Subject: [PATCH 2/3] drm/amd/display: dumb_abm_lcd: avoid missing-prototype warnings

From: Arnd Bergmann <[email protected]>

The dmub_abm_set_ambient_level() function has no caller and can
just be removed, the other ones have a declaration in the
header file and just need to see the prototype:

The only references to these variables were removed, so they now cause
warnings and have to be removed as well:

This has already been fixed, as of commit 1adb4dd5bd4b
("drm/amd/display: Remove unused variables in dcn21_hwseq.c") in
amd-staging-drm-next.
