| Subject: ACPI: Always report a sync event after a lid state change |
| To: stable@kernel.org |

| upstream commit df316e939100e789b3c5d4d102619ccf5834bd00 |
| |
| Currently not always an EV_SYN event is reported to userland |
| after the EV_SW SW_LID event has been sent. This is easy to verify |
| by using “input-events” from input-utils and just closing and opening |
| the lid. |
