Subject: drm/radeon: Don't unreserve twice on failure to validate.
X-Git-Tag: v3.12-rc1~13716^2~12
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=e46074effd5510e7a8fe34b93828d98a50835da2;p=kernel%2Fkernel-generic.git

drm/radeon: Don't unreserve twice on failure to validate.

This is done later in radeon_object_list_unvalidate(). Doing it twice triggers
a BUG in TTM, rendering X on KMS unusable until reboot.
