[PATCH 5.10 408/663] drm/msm: Fix MSM_INFO_GET_IOVA with carveout

[Greg Kroah-Hartman]

From: Iskren Chernev <iskren.chernev@xxxxxxxxx>

[ Upstream commit 6cefa31e810404dafdfcdb94874146cea11626c2 ]

The msm_gem_get_iova should be guarded with gpu != NULL and not aspace
!= NULL, because aspace is NULL when using vram carveout.

Fixes: 933415e24bd0d ("drm/msm: Add support for private address space instances")
