From d4f6c6f15a1f57e10374cf1a457f4eab5933bd0c Mon Sep 17 00:00:00 2001 From: Phil Reid Date: Fri, 24 Feb 2017 11:12:51 +0800 Subject: [PATCH] rtc: ds3232: Call device_init_wakeup before device_register The wakealarm attribute is currently not exposed in the sysfs interface as the device has not been set as doing wakealarm when device_register is called. Changing the order of the calls fixes that problem. Interrupts are cleared in check_rtc_status prior to requesting the interrupt. This is only set if an irq is defined. If irq registration fails then set wakeup_capable to false. With this change the sysfs wakealarm attribute will be left visible but it is non functional. rtcwake still returns that the device is not enabled for wakeup.
