[Intel-gfx] [bug report] drm/i915: Use the async worker to avoid reclaim tainting the ggtt->mutex

[Dan Carpenter]

Hello Chris Wilson,

The patch e3793468b466: "drm/i915: Use the async worker to avoid
reclaim tainting the ggtt->mutex" from Jan 30, 2020, leads to the
following static checker warning:

	drivers/gpu/drm/i915/i915_vma.c:356 i915_vma_wait_for_bind()
	warn: 's64max' cannot fit into 'bool'

drivers/gpu/drm/i915/i915_vma.c
   345  int i915_vma_wait_for_bind(struct i915_vma *vma)
   346  {
   347          int err = 0;
   348  
   349          if (rcu_access_pointer(vma->active.excl.fence)) {
   350                  struct dma_fence *fence;
   351  
   352                  rcu_read_lock();
   353                  fence = dma_fence_get_rcu_safe(&vma->active.excl.fence);
   354                  rcu_read_unlock();
   355                  if (fence) {
   356                          err = dma_fence_wait(fence, MAX_SCHEDULE_TIMEOUT);
                                                            ^^^^^^^^^^^^^^^^^^^^
The dma_fence_wait() takes a bool, not a timeout value.

   357                          dma_fence_put(fence);
   358                  }
   359          }
   360  
   361          return err;
   362  }
