[PATCH v2 17/17] RTC: rtctest: Change no IRQ detection for RTC_IRQP_SET
From: Andrey Smirnov
Date: Tue Jun 21 2016 - 03:28:10 EST
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.
