4 Subject: [PATCH 4/9] leds: Provide stubs for when CLASS_LED & NEW_LEDS are
5 disabled
6
7 Provide stubs for devm_led_classdev_register_ext() and
8 led_init_default_state_get() so that LED drivers embedded within other
9 drivers such as PHYs and Ethernet switches still build when LEDS_CLASS
10 or NEW_LEDS are disabled. This also helps with Kconfig dependencies,
11 which are somewhat hairy for phylib and mdio and only get worse when
12 adding a dependency on LED_CLASS.
