[ Upstream commit e8f0dc024ce55451ebd54bad975134ba802e4fcc ]
The rtl8366rb_led_group_port_mask() function always returns LED port
bit in LED group 0; the switch statement returns the same thing in all
non-default cases.
This means that the driver does not currently support configuring LEDs
in non-zero LED groups.
Fix this.

net: dsa: rtl8366rb: Fix compilation problem2025-02-24T09:14:42ZLinus Walleijlinus.walleij@linaro.org2025-02-20T18:48:15Zurn:sha1: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.
