gcc -Wextra warns about a function taking an enum argument being called with a bool:
drivers/gpu/drm/amd/amdgpu/../display/modules/color/color_gamma.c: In function 'apply_degamma_for_user_regamma': drivers/gpu/drm/amd/amdgpu/../display/modules/color/color_gamma.c:1617:29: warning: implicit conversion from 'enum <anonymous>' to 'enum dc_transfer_func_predefined' [-Wenum-conversion] 1617 | build_coefficients(&coeff, true);
It appears that a patch was added using the old calling conventions after the type was changed, and the value should actually be 0 (TRANSFER_FUNCTION_SRGB) here instead of 1 (true).
This looks correct to me. Harry, Leo?
