6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Vicki Pfau <vi@xxxxxxxxxxx>
[ Upstream commit 34281b4d916f167a6f77975380e1df07f06248b7 ]
The original implementation of this driver incorrectly guessed the function of
this register. It's not only unnecessary to write to this register for lizard
mode but actually counter-productive since it overwrites whatever previous
value was intentionally set, for example by Steam.
