platform/x86: ideapad-laptop: handle ACPI event 1
On Ideapad laptops, ACPI event 1 is currently not handled. Many models log "ideapad_laptop: Unknown event: 1" every 20 seconds or so while running on battery power. Some convertible laptops receive this event when switching in and out of tablet mode. This adds and additional case for event 1 in ideapad_acpi_notify to call ideapad_input_report(priv, vpc_bit), so that the event is reported to userspace and we avoid unnecessary logging. Fixes bug #107481 (https://bugzilla.kernel.org/show_bug.cgi?id=107481) Fixes bug #65751 (https://bugzilla.kernel.org/show_bug.cgi?id=65751) Signed-off-by: Zach Ploskey <zach@ploskey.com> Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com>
