    Subject[net-next PATCH v6 04/16] leds: Provide stubs for when CLASS_LED & NEW_LEDS are disabled
    Date
    From: Andrew Lunn <andrew@lunn.ch>

    Provide stubs for devm_led_classdev_register_ext() and
    led_init_default_state_get() so that LED drivers embedded within other
    drivers such as PHYs and Ethernet switches still build when LEDS_CLASS
    or NEW_LEDS are disabled. This also helps with Kconfig dependencies,
    which are somewhat hairy for phylib and mdio and only get worse when
    adding a dependency on LED_CLASS.
