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.
