linux-next: manual merge of the driver-core tree with the net-next tree

From: Stephen Rothwell

Hi Greg,

Today's linux-next merge of the driver-core tree got a conflict in
drivers/net/wireless/ath/ath9k/debug.c between commits 70e535ed0029
("ath9k: clean up debugfs print of reset causes"), 7b8aaead958e
("ath9k: restart hardware after noise floor calibration failure") and
325e18817668 ("ath9k: fix misc debugfs when not using chan context")
from the net-next tree and commit 631bee257bd5 ("ath: use seq_file api
for ath9k debugfs files") from the driver-core tree.

I fixed it up (see below) and can carry the fix as necessary (no action
is required).

Greg, I am not sure why those 2 commits are even in your tree. Do they
depend on something else in your tree?
