Hm, that's a bit unexpected. You are on a gen4 device, which means
we'll return the right error in the same function after a few more
register writes. But those are harmless.
On gen5+ we do more (call the pipe_control setup code), which could
potentially clobber the error code. So your patch looks

This commit add check for return value of init_ring_common() in the
init_render_ring(). Now, when failure is detected the error code is
propagated to the caller layer instead of being ignored.
I believe that this fix will have a positive impact on the oops that
I hit recently and which starts when
