Subject: drm/amd/display: Return the exact value for debugging
X-Git-Tag: v6.16-rc1~144^2~5^2~53
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=ea979dd40138e0132fb3e4372859a5efadce0f37;p=thirdparty%2Fkernel%2Fstable.git

drm/amd/display: Return the exact value for debugging

[Why]
It's unnecessary to set operation_result as invalid reply when
p_notify->result != AUX_RET_SUCCESS.

[How]
Set operation_result as p_notify->result to better understand
the reason for the error
