I tend to not want the patch in mainline. IMHO a wrong workaround that
fixes the issue only for 95% is worse than an unfixed driver.
Maybe when analysing more exact the outcome is that the patch is right,
but if there is a race condition somewhere in the code it might be that
there is still a bug. Not being able to reproduce the problem doesn't
necessarily imply that the introduced change is a real fix.

Best regards
Uwe
