Subject: [PATCH v2 0/7] regulator: core: locking cleanups, part 1/inf

This series aims to reduce regulator locking code complexity. There is
a consmetic fix (patch #6) included (applies to unexpected/unlikely
errors only). v2 adds a regulator_lock_contended() function to make the
ww_mutex locking sequence easier to understand.

Michał Mirosław (7):
  regulator/core: regulator_lock_nested: remove `lock`
  regulator/core: regulator_lock_nested: skip extra lock for -EDEADLK
  regulator/core: regulator_lock_nested: simplify nested locking
  regulator/core: regulator_resolve_supply: remove gotos
  regulator/core: regulator_lock_contended: wrap ww_mutex lock sequence
    restart
  regulator/core: regulator_lock_two: propagate error up
  regulator/core: regulator_lock_two: remove duplicate locking code
