Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
drm/amd/display: Fix disable_otg_wa logic<br />
<br />
[Why]<br />
When switching to another HDMI mode, we are unnecesarilly<br />
disabling/enabling FIFO causing both HPO and DIG registers to be set at<br />
the same time when only HPO is supposed to be set.<br />
<br />
This can lead to a system hang the next time we change refresh rates as<br />
there are cases when we don&#39;t disable OTG/FIFO but FIFO is enabled when<br />
it isn&#39;t supposed to be.<br />
<br />
[How]<br />
Removing the enable/disable FIFO entirely.
