Fabio, All,

Right when you sent this patch, we were discussing the exact same error
with Titouan, but about the virgl driver.

Applied to master, but with the following changes:

  - make it a generic fix, not tied to freedreno, reported by Fabio
  - rewrite commit log to explain the root cause
  - also reported about virgl, by Titouan

Please look at the new commit log I pushed for further details, and how
I eventually tweaked the file.

I'll try to push a fix upstream, so maybe next time we bump, we can
further relax the dependency by reverting the patch I applied.

Regards,
Yann E. MORIN.
