The driver is reporting a warning at kernel/time/timer.c:1096 due to calling

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
