    Subject[PATCH 3.18 154/185] hwmon: (pmbus/max8688) Accept negative page register values
    Date
    3.18-stable review patch.  If anyone has any objections, please let me know.

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

    From: Guenter Roeck <linux@roeck-us.net>

    [ Upstream commit a46f8cd696624ef757be0311eb28f119c36778e8 ]

    A negative page register value means that no page needs to be
    selected. This is used by status register evaluations and needs
    to be accepted.

    Fixes: da8e48ab483e1 ("hwmon: (pmbus) Always call _pmbus_read_byte in core driver")
