Hi !
This is somewhat of a recurring issue, some of my previous attempts on
lkml, I suspect, were just drowned in the noise. Eric, we had a quick

wait_for_completion_timeout returns unsigned long not int so the check for
<= 0 should be == 0 here.

wait_for_completion_timeout returns unsigned long not int so the check for
<= 0 should be == 0 here, and the type unsigned long. The function return
is set to -ETIMEDOUT to reflect the actual problem.
