Subject: drm/radeon: init lockup timeout on ring init
From: Christian König <[email protected]>
commit 48c0ac9911839daf188e4a0b6b132ac31050a241 upstream.
Reset the lockup timeout on ring (re-)initialisation.
Otherwise we get error messages like this on gpu resets:
[ 1559.949177] radeon 0000:01:00.0: GPU lockup CP stall for more than
1482270msec
