Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
drm/amd/display: prevent hang on link training fail<br />
<br />
[Why]<br />
When link training fails, the phy clock will be disabled. However, in<br />
enable_streams, it is assumed that link training succeeded and the<br />
mux selects the phy clock, causing a hang when a register write is made.<br />
<br />
[How]<br />
When enable_stream is hit, check if link training failed. If it did, fall<br />
back to the ref clock to avoid a hang and keep the system in a recoverable<br />
state.
