[PATCH 2/2] rtc: bd70528: Fix hour register mask

From: Matti Vaittinen
Date: Wed Oct 23 2019 - 07:48:15 EST


When RTC is used in 24H mode (and it is by this driver) the maximum
hour value is 24 in BCD. This occupies bits [5:0] - which means
correct mask for HOUR register is 0x3f not 0x1f. Fix the mask

Fixes: 32a4a4ebf768 ("rtc: bd70528: Initial support for ROHM bd70528 RTC")
