Subject: [PATCH] drm/amd/display: fix apply_degamma_for_user_regamma() warning

From: Arnd Bergmann <arnd@...db.de>

It appears that the wrong argument was removed in this call:

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:1694:36: error: implicit conversion from 'enum <anonymous>' to 'enum dc_transfer_func_predefined' [-Werror=enum-conversion]
 1694 |         build_coefficients(&coeff, true);

Fixes: 9b3d76527f6e ("drm/amd/display: Revert adding degamma coefficients")
