Merge tag 'regulator-fix-v5.4-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator

Pull regulator fixes from Mark Brown:
 "There are a few core fixes here around error handling and handling if
  suspend mode configuration and some driver specific fixes here but the
  most important change is the fix to the fixed-regulator DT schema
  conversion introduced during the last merge window.

  That fixes one of the last two errors preventing successful execution
  of "make dt_binding_check" which will be enormously helpful for DT
  schema development"
