Subject: [PATCH] Linux 3.8 compatibility hack |
| 21 |
|
| 22 |
Since the following commit, the device would not turn off because the power |
| 23 |
state is unknown. Until a fix is released in Linux (or until I know what |
| 24 |
better to do), I just assume the power state D0. |

ACPI / PM: Add check preventing transitioning to non-D0 state from D3. |
| 31 |
|
| 32 |
No power transitioning from D3 state up to a non-D0 state is allowed |
| 33 |
so make acpi_device_set_power() fail and complain if such a transition |
| 34 |
is attempted. |
