[ Upstream commit 39465cac283702a7d4a507a558db81898029c6d3 ]
Since size of 'header' pointer and '*header' structure is equal on 64-bit machines issue probably didn't cause any wrong behavior. But anyway, fixing typo is required.
Fixes: 7a73ba7469cb ("drm/vmwgfx: Use TTM handles instead of SIDs as user-space surface handles.")
