[ Upstream commit f15176b8b6e72ac30e14fd273282d2b72562d26b ]
When the kernel is compiled without LED framework support the rtl8366rb fails to build like this:
rtl8366rb.o: in function `rtl8366rb_setup_led': rtl8366rb.c:953:(.text.unlikely.rtl8366rb_setup_led+0xe8): undefined reference to `led_init_default_state_get' rtl8366rb.c:980:(.text.unlikely.rtl8366rb_setup_led+0x240): undefined reference to `devm_led_classdev_register_ext'
As this is constantly coming up in different randconfig builds, bite the bullet and create a separate file for the offending code, split out a header with all stuff needed both in the core driver and the leds code.
Add a new bool Kconfig option for the LED compile target, such that it depends on LEDS_CLASS=y || LEDS_CLASS=RTL8366RB which make LED support always available when LEDS_CLASS is compiled into the kernel and enforce that if the LEDS_CLASS is a module, then the RTL8366RB driver needs to be a module as well so that modprobe can resolve the dependencies.
