Subject: [PATCH 0/4] Provide event map helper for regulator drivers

Misc regulator fixes.

This series provides a trivial event map helper for regulator drivers,
new single_bit_set() (needed by the event map helper) and a fix to
regulator IRQ helper parameters.

Regulators which provide trivial notification IRQs can use generic IRQ
mapper. Trivial in this context means the IRQ only informs one type of
event, for one regulator.

The series also provides a bitop helper which checks if there is only
one bit set in given mask. This was believed to be useful also for
others outside the regulator framework.

Last patch is a fix for IRQ helper removing an unused struct member.

Matti Vaittinen (4):
  bitops: Add single_bit_set()
  regulators: Add regulator_err2notif() helper
  regulators: irq_helper: Provide helper for trivial IRQ notifications
  regulator: Drop unnecessary struct member
