    Subject[PATCH 5.5 311/367] mfd: bd70528: Fix hour register mask
    Date
    From: Matti Vaittinen <matti.vaittinen@fi.rohmeurope.com>

    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

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