[PATCH 5.5 311/367] mfd: bd70528: Fix hour register mask
From: Greg Kroah-Hartman
Date: Mon Feb 10 2020 - 07:55:32 EST
From: Matti Vaittinen <matti.vaittinen@xxxxxxxxxxxxxxxxx>
commit 6c883472e1c11cb05561b6dd0c28bb037c2bf2de upstream.
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
