3.16.54-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Alexandre Belloni alexandre.belloni@free-electrons.com
commit 74717b28cb32e1ad3c1042cafd76b264c8c0f68d upstream.
If there is any non expired timer in the queue, the RTC alarm is never set. This is an issue when adding a timer that expires before the next non expired timer.
Ensure the RTC alarm is set in that case.
