    Subject[PATCH 4.19 102/103] regulator: ab8500: Remove SYSCLKREQ from enum ab8505_regulator_id
    Date
    From: Stephan Gerhold <stephan@gerhold.net>

    commit 458ea3ad033fc86e291712ce50cbe60c3428cf30 upstream.

    Those regulators are not actually supported by the AB8500 regulator
    driver. There is no ab8500_regulator_info for them and no entry in
    ab8505_regulator_match.

    As such, they cannot be registered successfully, and looking them
    up in ab8505_regulator_match causes an out-of-bounds array read.

    Fixes: 547f384f33db ("regulator: ab8500: add support for ab8505")
