From 9f8f0c4f4cc6ce84bccc9211accb1f1bd1c762e6 Mon Sep 17 00:00:00 2001 From: Kars de Jong Date: Sat, 16 Nov 2019 12:05:48 +0100 Subject: [PATCH] rtc: msm6242: Fix reading of 10-hour digit commit e34494c8df0cd96fc432efae121db3212c46ae48 upstream. The driver was reading the wrong register as the 10-hour digit due to a misplaced ')'. It was in fact reading the 1-second digit register due to this bug. Also remove the use of a magic number for the hour mask and use the define for it which was already present.
