Messages in this thread Patch in this message | | | From | Guenter Roeck <> | Subject | [PATCH v3 28/47] power/reset: at91-poweroff: Register with kernel power-off handler | Date | Mon, 27 Oct 2014 08:55:35 -0700 |
| |
Register with kernel power-off handler instead of setting pm_power_off directly. Select default priority to reflect that the original code sets pm_power_off unconditionally.
Acked-by: Sebastian Reichel <sre@kernel.org> Signed-off-by: Guenter Roeck <linux@roeck-us.net> --- v3: - Replace poweroff in all newly introduced variables and in text with power_off or power-off as appropriate - Replace POWEROFF_PRIORITY_xxx with POWER_OFF_PRIORITY_xxx v2: - Added patch
