Subject: [PATCH] hwmon: pmbus: ibm-cffps depends on LEDS_CLASS
Date: Fri, 12 Jan 2018 16:49:00 +0100
Message-Id: <20180112154926.3646202-1-arnd@arndb.de>
Sender: linux-kernel-owner@vger.kernel.org

Building without CONFIG_LEDS_CLASS causes a link failure:

drivers/hwmon/pmbus/ibm-cffps.o: In function `ibm_cffps_probe':
ibm-cffps.c:(.text+0x4f4): undefined reference to `devm_of_led_classdev_register'

This adds the required dependency.

Fixes: f69316d62c70 ("hwmon: (pmbus) Add IBM Common Form Factor (CFF) power supply driver")
