From c8a22799c9c8993fb8a539444c1af4cd87de5a3c Mon Sep 17 00:00:00 2001 From: Bartosz Golaszewski Date: Fri, 3 Jan 2020 12:41:56 +0100 Subject: [PATCH] mfd: max77650: Select REGMAP_IRQ in Kconfig commit cb7a374a5e7a5af3f8c839f74439193add6d0589 upstream. MAX77650 MFD driver uses regmap_irq API but doesn't select the required REGMAP_IRQ option in Kconfig. This can cause the following build error if regmap irq is not enabled implicitly by someone else: ld: drivers/mfd/max77650.o: in function `max77650_i2c_probe': max77650.c:(.text+0xcb): undefined reference to `devm_regmap_add_irq_chip' ld: max77650.c:(.text+0xdb): undefined reference to `regmap_irq_get_domain' make: *** [Makefile:1079: vmlinux] Error 1 Fix it by adding the missing option.
