5.4-stable review patch. If anyone has any objections, please let me know. ------------------ From: Steven 'Steve' Kendall <skend@xxxxxxxxxxxx> commit 7e1e206b99f4b3345aeb49d94584a420b7887f1d upstream. In recent HP UEFI firmware (likely v2.15 and above, tested on 2.27), these pins are incorrectly set for HDMI/DP audio. Tested on HP MP9 G4 Retail System AMS. Tested audio with two monitors connected via DisplayPort.
