[net-next PATCH v5 04/15] leds: Provide stubs for when CLASS_LED is disabled

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Andrew Lunn <andrew@xxxxxxx>

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
is 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.
