[ Upstream commit dbb60031dd0c2b85f10ce4c12ae604c28d3aaca4 ]
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).
Fixes: 55a01d4023ce ("drm/amd/display: Add user_regamma to color module")
