[PATCH 4.9 023/102] rtc: max8907: add missing select REGMAP_IRQ

From: Greg Kroah-Hartman
Date: Wed Apr 01 2020 - 12:35:41 EST


From: Corentin Labbe <clabbe@xxxxxxxxxxxx>

commit 5d892919fdd0cefd361697472d4e1b174a594991 upstream.

I have hit the following build error:

armv7a-hardfloat-linux-gnueabi-ld: drivers/rtc/rtc-max8907.o: in function `max8907_rtc_probe':
rtc-max8907.c:(.text+0x400): undefined reference to `regmap_irq_get_virq'

max8907 should select REGMAP_IRQ

If you say yes here you will get support for the
