Merge tag 'regmap-3.4-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap
Pull two more small regmap fixes from Mark Brown:
- Now we have users for it that aren't running Android it turns out
that regcache_sync_region() is much more useful to drivers if it's
exported for use by modules. Who knew?
- Make sure we don't divide by zero when doing debugfs dumps of
rbtrees, not visible up until now because everything was providing at
least some cache on startup.
