ACPI / ACPICA: Do not attempt to disable GPE when installing handler
Commit 0f849d2cc6863c7874889ea60a871fb71399dd3f (ACPICA: Minimize the differences between linux GPE code and ACPICA code base) introduced a change attempting to disable a GPE before installing a handler for it in acpi_install_gpe_handler() which was incorrect. First, the GPE disabled by it is never enabled again (except during resume) which leads to battery insert/remove events not being reported on the Maxim Levitsky's machine. Second, the disabled GPE is still reported as enabled by the sysfs interface that only checks its enable register's enable_for_run mask. Revert this change for now, because it causes more damage to happen than the bug it was supposed to fix. Signed-off-by: Rafael J.
