Subject: drm/virtio: allocate fences with GFP_KERNEL
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=4d8979b3a6966e8d4d600f1783b58e77c2dbc0ff;p=openwrt%2Fstaging%2Fblogic.git

drm/virtio: allocate fences with GFP_KERNEL

It was changed to GFP_ATOMIC in commit ec2f0577c (add & use
virtio_gpu_queue_fenced_ctrl_buffer) because the allocation happened
with a spinlock held.  That was no longer true after commit
9fdd90c0f (add virtio_gpu_alloc_fence()).
