Here is the big staging tree update for the 3.7-rc1 merge window.
There are a few patches in here that are outside of the staging area,
namely HID and IIO patches, but all of them have been acked by the
relevant subsystem maintainers. The IIO stuff is still coming in
through this tree as it hasn't entirely moved out of the staging tree,
but is almost there.
Other than that, there wa a ton of work on the comedi drivers to make
them more readable and the correct style. Doing that removed a lot of
code, but we added a new driver to the staging tree, so we didn't end up
with a net reduction this time around:
662 files changed, 51649 insertions(+), 26582 deletions(-)
All of these patches have been in the linux-next tree already.

The original code is equivalent to:

so it just sets .flags to zero. We should be ORing the values together

In drivers/staging/rtl8192e/rtllib_softmac.c::rtllib_rx_assoc_resp()
we allocate memory for 'network' with kzalloc() and then proceed to
zero the already zeroed mem we got from kzalloc() with
memset(). That's redundant, so remove the memset()
We also fail to kfree() the memory we allocated for 'network' if we do not enter
if (ieee->current_network.qos_data.supported == 1) {
and the variable then goes out of scope.
To fix that I simply moved the kfree() that was inside that 'if'
statement to instead be just after it. It then covers both the case
where we take the branch and when we don't.

Convert rtllib from registering the crypt drivers against rtllib_crypt
and instead register the against lib80211. The crypto functions have
R- prepended (R-CCMP, R-TKIP, R-WEP) so they will not clash with the
lib80211 versions.
We cannot use the lib80211 crypt drivers since the rtl8192e has some
hardware support that is not handled by the lib80211 crypt drivers.

Now that the rtl8192e driver is split up, it makes sense to keep the
rtllib code in one directory and the rtl8192e specific code in
another. This patch contains the split and the fixup of includes.
Since rtl_core.h already included rtllib.h and dot11d.h, rtl_core.h
was updated to point to the parent directory. All other references to
rtllib.h and dot11d.h in the rtl8192e specific code where deleted
rather than fixed. This leaves just one file that needs to know the
real location of the rtllib includes.

Now that they are proper modules, the init and exit functions do not
need to be called directly. Also, the rtllib_*_null functions are not
