Fixes: 5e386b574cf7e1 ("drm/radeon: fix missing bo reservation") Cc: [email protected] Cc: Christian König <[email protected]> Cc: Alex Deucher <[email protected]> Signed-off-by: Quentin Casasnovas <[email protected]>Sorry I missed this. It looks like we probably want an updated version for newer kernels where radeon_vm_init() can fail as well.
I've rebased the stuff and added the missing free on vm failure as well. Patch is on the list and in my 3.15 queue. Christian.
