Subject: [PATCH 2/8] Revert "rtc: sc27xx: Always read normal alarm when registering RTC device"

From: Bartosz Golaszewski <bgolaszewski@...libre.com>

This reverts commit 3822d1bb0df18aa28930f19bc46e0704aea1be0f.

The registered field in struct rtc_device is not supposed to be used by
drivers and is going to be removed soon. In this function it will be
always 0 so the check is useless anyway.
