When IGC is built-in but LEDS_CLASS is a loadable module, there is
a link failure:
x86_64-linux-ld: drivers/net/ethernet/intel/igc/igc_leds.o: in function `igc_led_setup':
igc_leds.c:(.text+0x75c): undefined reference to `devm_led_classdev_register_ext'
Add another dependency that prevents this combination.

Ops, sorry. I tried to build all different combinations, but obviously
failed. Thanks for fixing this.

Should it be ordered as the line above?

I don't know kbuild that well, but would this cover LEDS_CLASS=n with IGC=m?
There are Similar checks in the file [1][2] that would transpose to
depends on IGC && LEDS_CLASS && !(IGC=y && LEDS_CLASS=m)
which should cover that and keep the checks in the file consistent. IMO
a little more readable as well.
Thanks,
Tony

The 'depends on LEDS_CLASS' take care of that.

Right, that works as well. I find the negative dependencies
slightly more confusing, they should do the same thing here.
Please apply whichever version makes most sense to you then.
