Subject: linux-next: build failure after merge of the leds tree

Hi Bryan,

After merging the leds tree, today's linux-next build (x86_64
allmodconfig) failed like this:

drivers/built-in.o: In function `lp55xx_unregister_leds':
(.text+0x161dab): undefined reference to `led_classdev_unregister'

Caused by commit 14732b162d34 ("leds-lp55xx: use
lp55xx_unregister_leds()").

lp5521/5523").

I have used the leds tree from next-20130122 for today.

Bryan and Stephen,

Sorry for this errors. A patch has been sent.
https://lkml.org/lkml/2013/1/23/14

And I've got few warnings about leds-lp5521/5523 drivers, separate patchset will
be submitted soon.

Best Regards,
Milo
