The driver is reporting a warning at kernel/time/timer.c:1096 due to calling
del_timer_sync() while in interrupt mode. Such warnings are fixed by calling
del_timer() instead.

Hi,

I haven't been using kernel v4.1 so I haven't seen this warning, but looking
at the code it seems to originate from the two recent patches to remove
_cancel_timer and _cancel_timer_ex. I see that there's another patch in lkml [1]
that changes del_timer_sync back to del_timer in more places. Perhaps it
could prevent other warnings like this in the future.

Regards,
Haggai

Yes, the script kiddies make changes they do not understand and screw everything 
up. Unfortunately, I did not catch these in review. I think I will submit V2 and 
blast the contributor.
