Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
drm/bridge: it6505: Initialize AUX channel in it6505_i2c_probe<br />
<br />
During device boot, the HPD interrupt could be triggered before the DRM<br />
subsystem registers it6505 as a DRM bridge. In such cases, the driver<br />
tries to access AUX channel and causes NULL pointer dereference.<br />
Initializing the AUX channel earlier to prevent such error.
