Merge tag 'regmap-v3.11-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap

Pull regmap fixes from Mark Brown:
 "Two changes here:

   - Fix a bug in the rbtree code which could cause it to create two
     different cache entries for the same register by adding a single
     register at a time to the cache.  This isn't awesome for
     performance but it's non-invasive which we need for this late in
     the release cycle and the I/O costs we're trying to avoid are high.

   - Add another header used in the !CONFIG_REGMAP stubs where we had
     been relying on implicit inclusion"
