Subject: [PATCH 46/52] Convert rtc drivers to use the alarm_irq_enable method
|
|
|
|
Old rtc drivers use the ioctl method instead of the alarm_irq_enable
|
|
method for enabling alarm interupts. With the new virtualized RTC
|
|
rework, its important for drivers to use the alarm_irq_enable instead.
|
|
|
|
This patch converts the drivers that use the AIE ioctl method to
|
|
use the alarm_irq_enable method.
