drm/connector: hdmi: Fix memory leak in drm_display_mode_from_cea_vic()
Details

In the Linux kernel, the following vulnerability has been resolved:

drm/connector: hdmi: Fix memory leak in drmdisplaymodefromcea_vic()

modprobe drmconnectortest and then rmmod drmconnectortest, the following memory leak occurs.

The mode allocated in drmmodeduplicate() called by drmdisplaymodefromcea_vic() is not freed, which cause the memory leak:
