[PATCH 0/4] Atheros IEEE 802.11n ath9k driver

[Luis R. Rodriguez]

This series of patches adds the ath9k driver which adds support
for all Atheors IEEE 802.11n chipsets along some new linked list
helpers.

More information about this driver is available at:

http://wireless.kernel.org/en/users/Drivers/ath9k

Our mailing list for this driver is:

[PATCH 1/4] list.h: Add list_splice_tail() and list_splice_tail_init()

[Luis R. Rodriguez]

If you are using linked lists for queues list_splice() will not do what
you would expect even if you use the elements passed reversed. We need
to handle these differently. We add list_splice_tail() and
list_splice_tail_init()

No signed off yet, I haven't even read in detail through the whole
driver.  Same is probably true for most other people on this
list.

That beeing said I'm not really in a position to sign off either as
I'm not the mainter nor a major contributor to the patch.

Sorry I had meant you had patches in with your name. Just wanted to
provide credit for that, that's all.
