From 0a553cbabd369c52b921fced5e1a1ea3e60e0e0d Mon Sep 17 00:00:00 2001 From: Andrey Smirnov Date: Tue, 21 Jun 2016 00:22:50 -0700 Subject: [PATCH] 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.
