From: Arnd Bergmann Date: Tue, 3 Nov 2015 13:51:29 +0000 (+0100) Subject: arcnet/com20020: add LEDS_CLASS dependency X-Git-Tag: v4.9.8~3303^2~10 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=754107e34165373b3696620cef344227b10eaa99;p=platform%2Fkernel%2Flinux-rpi3.git arcnet/com20020: add LEDS_CLASS dependency The newly added led trigger support in the com20020-pci driver causes build errors when CONFIG_LEDS_CLASS is disabled: drivers/built-in.o: In function `com20020pci_probe': (.text+0x185dc4): undefined reference to `devm_led_classdev_register' (.text+0x185dd8): undefined reference to `devm_led_classdev_register' This adds a Kconfig dependency to prevent the invalid configurations. Other drivers appear to be split 50:50 between 'select' and 'depends on' for this symbol, I picked 'depends on' as I could not find a common policy and it generally causes fewer problems.
