- Subject: [PATCH 4/9] leds: Provide stubs for when CLASS_LED & NEW_LEDS are
- disabled
- 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.
