Subject: [PATCH v2 0/3] ACPI / button: Clarify initial lid state

The initial _LID returning value is not reliable after boot/resume because
the BIOS vendors may implement it by returning a cached value that is only
updated when a lid notification is received.
This causes strange things happening after resuming. This patchset fixes
the issue according to this fact.

Lv Zheng (3):
  ACPI / button: Remove initial lid state notification
  ACPI / button: Refactor functions to eliminate redundant code
  ACPI / button: Send "open" state after boot/resume
