Commit f790bd9c authored by Linus Torvalds's avatar Linus Torvalds

Merge tag 'regulator-v4.11' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator

Pull regulator updates from Mark Brown:
 "Quite a lot of work going on the core this release, mainly around
  system initialization, but a quiet release for drivers:

   - fixes for registration of multiple regulators on a PMIC from Javier
     Martinez Canillas and Jon Hunter.

   - cleanups to the regulator_get() code from Dmitry Torokhov

   - lots of constifcation of structs from Bhumika Goyal

   - support for Motorola CPCAP regulators from Tony Lindgren"
