This patch series fixes some issues around the battery hook handling
inside the ACPI battery driver and the dell-laptop driver.

The first patch simplifies the locking during battery hook removal as
a preparation for the second patch which fixes a possible crash when
unregistering a battery hook.

The third patch allows the dell-laptop driver to handle systems with
multiple batteries.

All patches where tested on a Dell Inspiron 3505 and appear to work.

Chnages since v2:
- drop boolean flag and use list head instead in patch 2
- drop mjg59@srcf.ucam.org from the CC list since the underlying
adress seems to trigger random errors in proccessing (help?)

Changes since v1:
- fix the underlying issue inside the ACPI battery driver
- reword patch for dell-laptop

Armin Wolf (3):
  ACPI: battery: Simplify battery hook locking
  ACPI: battery: Fix possible crash when unregistering a battery hook
  platform/x86: dell-laptop: Do not fail when encountering unsupported
    batteries
