Pull regulator fixes from Mark Brown:
 "bd9571mwv regulator fixes for v5.12.

  A set of driver specific fixes here, the main one is a fix to not try
  to set unsupported voltages on this device. The other two patches
  clean up the error handling and eliminate the possibility that we
  could overflow the page when writing sysfs output (which AFAICT wasn't
  an issue but better to be sure)"

* tag 'regulator-fix-v5.12-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator:
  regulator: bd9571mwv: Convert device attribute to sysfs_emit()
  regulator: bd9571mwv: Fix regulator name printed on registration failure
  regulator: bd9571mwv: Fix AVS and DVFS voltage range
