[PATCH next] drm/msm/dpu: fix error pointer dereference in msm_kms_init_aspace()

[Dan Carpenter]

If msm_gem_address_space_create() fails, then return right away.
Otherwise it leads to a Oops when we dereference "aspace" on the next
line.

Fixes: 2d215d440faa ("drm/msm: register a fault handler for display mmu faults")
