[PATCH xf86-video-ati] modesetting: Skip no-longer-present connectors when resetting BAD links

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Keith Packard <keithp@xxxxxxxxxx>

Outputs may have NULL mode_output (connector) pointers if the
connector disappears while the server is running. Skip these when
resetting outputs with BAD link status.

(Ported from xserver commit 37f4e7651a2fd51efa613a08a1e705553be33e76)
