Revision 682354d4e0bf9a28f11b52ef9be7fb38b901bd5c authored by Arnd Bergmann on 27 February 2015, 23:51:48 UTC, committed by Linus Torvalds on 28 February 2015, 17:57:51 UTC
The newly added ds1685 driver causes a build error when enabled without CONFIG_RTC_INTF_DEV: drivers/rtc/rtc-ds1685.c:919:22: error: 'ds1685_rtc_alarm_irq_enable' undeclared here (not in a function) .alarm_irq_enable = ds1685_rtc_alarm_irq_enable, Apparently the driver was incorrectly changed to reflect the interface change from 16380c153a69c ("RTC: Convert rtc drivers to use the alarm_irq_enable method"), which removed the respective #ifdef from all other rtc drivers. This does the same change that was merged for the other drivers before and removes the #ifdef, allowing the interrupts to be enabled through the in-kernel rtc interface independent of the existence of /dev/rtc.
