Subject[PATCH 3.11 171/182] drm/radeon: memory leak on bo reservation failure. v2
Date
3.11.10.9 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Quentin Casasnovas <quentin.casasnovas@oracle.com>

commit 74073c9dd29905645feb6dee03c144657a9844cd upstream.

On bo reservation failure, we end up leaking fpriv.

v2 (chk): rebased and added missing free on vm failure as well

Fixes: 5e386b574cf7e1 ("drm/radeon: fix missing bo reservation")

[ luis: backported to 3.11:
- radeon_vm_init() returns a value only after commit 6d2f294
"drm/radeon: use normal BOs for the page tables v4", which is not
in 3.11 kernel, thus dropped 1st chunk of commit ]
