Subject: [PATCH 2/2] rtc: bd70528: Fix hour register mask
Date: Wed, 23 Oct 2019 14:47:51 +0300 [thread overview]
Message-ID: <20191023114751.GA14100@localhost.localdomain> (raw)
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")
