Merge tag 'regulator-fix-v6.1-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator

Pull regulator fixes from Mark Brown:
 "This is more changes than I'd like this late although the diffstat is
  still fairly small, I kept on holding off as new fixes came in to give
  things time to soak in -next but should probably have tagged and sent
  an additional pull request earlier.

  There's some relatively large fixes to the twl6030 driver to fix
  issues with the TWL6032 variant which resulted from some work on the
  core TWL6030 driver, a couple of fixes for error handling paths
  (mostly in the core), and a nice stability fix for the sgl51000 driver
  that's been pulled out of a BSP"
