Hi Gustavo,

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

drivers/net/ieee802154/at86rf230.c: In function 'at86rf230_s

Caused by commit

  890acf8330ca ("at86rf230: add debugfs support")

interacting with commit

  6798a8caaf64 ("fs/seq_file: convert int seq_vprint/seq_printf/etc... returns 
to void")

from Linus' tree (as you were warned it would).

I applied the patches that Andrew has had in his post merge series
(but I think you were sent a rolled up version):
