Thanks Binoy, but we already submitted a patch for this issue on June 11,
and are currently awaiting its acceptance into staging.  See:
* [PATCH RESEND 12/28] staging: unisys: visorbus: Make visordriver_callback_lock a mutex
(http://driverdev.linuxdriverproject.org/pipermail/driverdev-devel/2016-June/090861.html)
* [PATCH RESEND 00/28] staging: unisys: fix visorbus & visorinput issues raised by tglx
(http://driverdev.linuxdriverproject.org/pipermail/driverdev-devel/2016-June/090854.html)
