[PATCH 02/10] drm/qxl: more fence wait rework

From: Gerd Hoffmann
Date: Tue Feb 16 2021 - 06:39:51 EST


Move qxl_io_notify_oom() call into wait condition.
That way the driver will call it again if one call
wasn't enough.

Also allows to remove the extra dma_fence_is_signaled()
check and the goto.
