Subject: [PATCHv4 0/9] extcon: Support devm_extcon_dev_allocate/free()

This patchset add devm_extcon_dev_allocate/free() for the resource management
of extcon device. And devm_extcon_dev_allocate() handles all of supported cables.

Changes from v3:
- Change return value of extcon_dev_allocate()/devm_extcon_dev_allocate()
  if failed to allocate the memory of extcon device (NULL -> ERR_PTR(-ENOMEM))
- All of extcon provier drivers check return value using IS_ERR() macro
- Fix the description of function due to changing return type if failure

Changes from v2:
- Resolve bisectable issue about patch-1
  extcon: Add extcon_dev_allocate/free() to control the memory of extcon device
- extcon_dev_allocate/free() don't handle all behaviors for supported cables

Changes from v1:
- Rebase it on latest extcon-next branch
