    arcnet/com20020: add LEDS_CLASS dependency · 754107e3
    Arnd Bergmann authored
    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.
