    Subject[PATCH 4.16 263/272] regmap: Correct comparison in regmap_cached
    Date
    4.16-stable review patch.  If anyone has any objections, please let me know.

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

    From: Charles Keepax <ckeepax@opensource.cirrus.com>

    [ Upstream commit 71df179363a5a733a8932e9afb869760d7559383 ]

    The cache pointer points to the actual memory used by the cache, as the
    comparison here is looking for the type of the cache it should check
    against cache_type.

    Fixes: 1ea975cf1ef5 ("regmap: Add a function to check if a regmap register is cached")
