  [PATCH v2 17/17] RTC: rtctest: Change no IRQ detection for RTC_IRQP_SET Andrey Smirnov <andrew.smirnov@gmail.com> - 2016-06-21 09:30 +0200

#1427399 — [PATCH v2 17/17] RTC: rtctest: Change no IRQ detection for RTC_IRQP_SET

A call to ioctl(..., RTC_IRQP_SET, ...) should never result in
ENOTTY. All new style RTC drivers implement it and all of the old style
drivers return EINVAL when they don't support periodic IRQs.
