Subject: regmap: Reset device debugfs when reinitialising the cache
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=a24f64a648376766497fddd8bc24b1ca5b906431;p=mv-sheeva.git

regmap: Reset device debugfs when reinitialising the cache

Most of the data exposed via debugfs is for or from the cache so reset
all the debugfs configuration to make sure everything is up to date with
the latest configuration, especially if we're changing cache type.
