Subject: [patch] drm/amdgpu/virt: double free in amdgpu_map_static_csa()
Date: Tue, 07 Feb 2017 13:16:51 +0000 [thread overview]
Message-ID: <20170207131651.GB27416@mwanda> (raw)
The amdgpu_vm_bo_rmv() function frees "bo_va" so we shouldn't free it
a second time.
Fixes: 4e4bbe7343a6 ("drm/amdgpu:add new file for SRIOV")
Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com>
