  gpio: aggregator: simplify aggr_parse() with scoped bitmap

Koichiro Den (12):
  gpio: introduce utilities for synchronous fake device creation
  gpio: aggregator: protect driver attr handlers against module unload
  gpio: aggregator: reorder functions to prepare for configfs
    introduction
  gpio: aggregator: unify function naming
  gpio: aggregator: add gpio_aggregator_{alloc,free}()
  gpio: aggregator: introduce basic configfs interface
  UBUNTU: [Config] updateconfigs for DEV_SYNC_PROBE
  gpio: aggregator: rename 'name' to 'key' in gpio_aggregator_parse()
  gpio: aggregator: expose aggregator created via legacy sysfs to
    configfs
  gpio: aggregator: cancel deferred probe for devices created via
    configfs
