[PATCH 0/2] Fix a false lockdep warning on vmwgfx

[Thomas Hellstrom]

The commit "drm/ttm: make ttm reservation calls behave like reservation calls"
introduced a false lockdep warning on vmwgfx that hit on surface eviction,
due to a recursive reservation.
The fix silences the warning by using a tryreserve, which is not optimal, but
will do for now
