From 519efa98051717479ff3d0b6be996e112e7a87ff Mon Sep 17 00:00:00 2001 From: Andrey Smirnov Date: Tue, 21 Jun 2016 00:22:49 -0700 Subject: [PATCH] rtc: rtctest: Change no IRQ detection for RTC_IRQP_READ A call to ioctl(..., RTC_IRQP_READ, ...) 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.
