Subject: drm/amd/display: Remove Phantom Pipe Check When Calculating K1 and K2
From: Austin Zheng <austin.zheng@xxxxxxx>
commit 1966bbfdfe476d271b338336254854c5edd5a907 upstream.
[Why]
K1 and K2 not being setting properly when subVP is active.
[How]
Have phantom pipes use the same programing as the main pipes without
checking the paired stream
