From 406bf31893163cbe5b0b03a281685c7dc95c9380 Mon Sep 17 00:00:00 2001 From: Alexander Holler Date: Thu, 14 Nov 2013 14:32:00 -0800 Subject: [PATCH] drivers/rtc/rtc-hid-sensor-time.c: enable HID input processing early Enable the processing of HID input records before the RTC will be registered, in order to allow the RTC register function to read clock. Without doing that the clock can only be read after the probe function has finished.
