Hi Andrew,

Thanks for the patch.

Please address the issue [1] raised by test bot and resubmit.

Thanks,

It looks like some systems use 'gpio_led_register_device' to make an
in-memory copy of their LED device table so the original can be removed
as .init.rodata. This doesn't necessarily depend on the LED subsystem
but it kind of seems useless when the rest of the subsystem is disabled.

One solution could be to use a dummy 'gpio_led_register_device' when the
subsystem is not enabled.

It sounds good. Please add a no-op version of gpio_led_register_device()
to include/leds.h, in a separate patch.

Thanks,
Jacek Anaszewski

Another is just to remove the five or so uses
of 'gpio_led_register_device' and have those systems register LED device
tables like other systems do.

If nether of these are acceptable then this patch can be dropped from
this series for now.

Thanks,
Andrew

When CONFIG_NEW_LEDS is not set make will still descend into the leds
directory but nothing will be built. This produces unneeded build
artifacts and messages in addition to slowing the build. Fix this here.
