Merge tag 'regmap/range' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap into asoc-wm2200
regmap: Range API changes A bunch of updates to the regmap range support, the most important ones being to rename "n_ranges" to "num_ranges" for consistency and to allow block writes to cross page boundaries, making things more transparent.
