Subject: rtc: rtctest: Change no IRQ detection for RTC_IRQP_SET
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=0a553cbabd369c52b921fced5e1a1ea3e60e0e0d;p=deliverable%2Flinux.git

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.
