This reverts commit ab6cef1d14475f1af33da99a6774626f73d278b6.
|

|
||
Temporary fix to compile error:
|
||
/srv/source/drivers/power/reset/odroid-reboot.c: In function ‘odroid_restart_probe’:
|
||
/srv/source/drivers/power/reset/odroid-reboot.c:141:3: error: ‘arm_pm_restart’
|
||
undeclared (first use in this function); did you mean ‘alarm_restart’?
|
||
141 | arm_pm_restart = do_odroid_restart;
|
||
| ^~~~~~~~~~~~~~
|
||
| alarm_restart
|
||
/srv/source/drivers/power/reset/odroid-reboot.c:141:3: note: each
|
||
undeclared identifier is reported only once for each function it appears in
|
