Documentation/amdgpu: Fix duplicate declaration

2024-07-16T15:45:22+00:00

Address the below kernel doc warning: Documentation/gpu/amdgpu/display/display-manager:134: drivers/gpu/drm/amd/display/dc/inc/hw/mpc.h:3: WARNING: Duplicate C declaration, also defined at gpu/amdgpu/display/dcn-blocks:101. Declaration is '.. c:struct:: mpcc_blnd_cfg'. Documentation/gpu/amdgpu/display/display-manager:146: drivers/gpu/drm/amd/display/dc/inc/hw/mpc.h:3: WARNING: Duplicate C declaration, also defined at gpu/amdgpu/display/dcn-blocks:3. Declaration is '.. c:enum:: mpcc_alpha_blend_mode'. To address the above warnings, this commit uses the 'no-identifiers' option in the dcn-blocks to avoid duplication with the previous use of this function doc in the display-manager file. Finally, replaces the deprecated ':function:' in favor of ':identifiers:'.

Declaration is '.. c:struct:: surface_flip_registers'. This error happened due to a copy-and-paste where the same file path was duplicated multiple times to a different set of blocks. This commit addresses this issue by using the correct file path. Cc: Alex Deucher Acked-by: Alex Deucher Reported-by: Stephen Rothwell Signed-off-by: Rodrigo Siqueira Signed-off-by: Alex Deucher
