Subject: [PATCH 3.12 086/181] drm/radeon: memory leak on bo reservation failure. v2

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

3.12-stable review patch.  If anyone has any objections, please let me know.

===============

commit 74073c9dd29905645feb6dee03c144657a9844cd upstream.

On bo reservation failure, we end up leaking fpriv.

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