Hi all,

After merging the hid tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:

ld: drivers/hid/hid-lg-g15.o: in function `.lg_g15_probe':
hid-lg-g15.c:(.text+0x1a1c): undefined reference to `.devm_led_classdev_register_ext'
ld: hid-lg-g15.c:(.text+0x1c68): undefined reference to `.devm_led_classdev_register_ext'

Caused by commit

  3a0275384c27 ("HID: Add driver for Logitech gaming keyboards (G15, G15 v2)")

For this build, CONFIG_HID_LOGITECH=y and CONFIG_LEDS_CLASS=m.

I have used the hid tree from next-20191003 for today.
