    Subject[033/104] regulator: aat2870: Fix the logic of checking if no id is matched in aat2870_get_regulator
    3.1-stable review patch.  If anyone has any objections, please let me know.

    ------------------

    From: Axel Lin <axel.lin@gmail.com>

    commit d4d6373c1109b11c8118340be97ae31b8f94d66a upstream.

    In current implementation, the pointer ri is not NULL if no id is matched.
    Fix it by checking i == ARRAY_SIZE(aat2870_regulators) if no id is matched.
