[ Upstream commit 37a78445763a5921bb54e9bad01937d0dfa521c1 ]
The ->ring_idx_mask variable is a u64 so static checkers, Smatch in this case, complain if the BIT() is not also a u64.
drivers/gpu/drm/virtio/virtgpu_ioctl.c:50 virtio_gpu_fence_event_create() warn: should '(1 << ring_idx)' be a 64 bit type?
