Subject: [PATCH 0/2] acpi/button: revert v4.10 behavior

The new default 'open' behavior for acpi_lid_initialize_state() is just
wrong. It breaks professional laptops with a docking station [1].

Booting the laptop with the LID closed is something common and now there
is no way of knowing the actual state of the LID switch at boot. Please
use a user-space solution as described in 2/2 if you really don't want to
add quirks in the kernel.

Cheers,
Benjamin
