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?
They do. The three commits below are related:
d32394f ath: ath9k: use debugfs_create_devm_seqfile() helper for
seq_file entrie
631bee2 ath: use seq_file api for ath9k debugfs files
98210b7 debugfs: add helper function to create device related seq_file
The ath patches were made to provide example of using the new helper
function and get some idea about code savings. Greg and John discussed
who would take them. I noticed other ath changes in net-next so I kinda
expected this email ;-)
Regards,
Arend

I just ran in to a problem with one of these commits.
On an Acer C720 laptop if a suspend is performed the screen freezes,
the machine locks up, and according to the indicator lights it does
not enter suspend. A hard reset is required to get it running again.
I have bisected the kernel and found that the following is the first bad
commit.
commit d32394fae95741d733b174ec1446f27765f80233
Author: Arend van Spriel<arend@xxxxxxxxxxxx>
Date: Sun Nov 9 11:32:00 2014 +0100
ath: ath9k: use debugfs_create_devm_seqfile() helper for seq_file
entries
Use the helper to get rid of the file operations per debugfs file.
The
struct ath9k_softc pointer is set as device driver data to be
obtained
in the seq_file read operation.

Let me know if I can do anything else to help.

I took a look at the patch that is causing this problem (d32394fae95).
My config negates everything in the patch except for a one line change
to ath9k/pci.c. If I remove this change (shown below) the problem goes
away.
Ok. But then it will likely crash when you cat one of the changed debugfs
files. Guess this commit needs to be reverted entirely.
What commit, d32394fae95741d733b174ec1446f27765f80233?
Indeed.
Regards,
Arend
