Joseph Jang 2a027d6bb6 selftest: rtc: Add to check rtc alarm status for alarm related test ... In alarm_wkalm_set and alarm_wkalm_set_minute test, they use different ioctl (RTC_ALM_SET/RTC_WKALM_SET) for alarm feature detection. They will skip testing if RTC_ALM_SET/RTC_WKALM_SET ioctl returns an EINVAL error code. This design may miss detecting real problems when the efi.set_wakeup_time() return errors and then RTC_ALM_SET/RTC_WKALM_SET ioctl returns an EINVAL error code with RTC_FEATURE_ALARM enabled. In order to make rtctest more explicit and robust, we propose to use RTC_PARAM_GET ioctl interface to check rtc alarm feature state before running alarm related tests. If the kernel does not support RTC_PARAM_GET ioctl interface, we will fallback to check the error number of (RTC_ALM_SET/RTC_WKALM_SET) ioctl call for alarm feature detection.
