Subject: radeon/kms: force rn50 chip to always report connected on analog output
From: Jerome Glisse <[email protected]>
commit 51861d4eebc2ddc25c77084343d060fa79f6e291 upstream.
Those rn50 chip are often connected to console remoting hw and load
detection often fails with those. Just don't try to load detect and
report connect.
