This is a note to let you know that I've just added the patch titled
staging: comedi: ni_daq_700: fix dio subdevice regression
to my staging git tree which can be found at
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging.git
in the staging-linus branch.
The patch will show up in the next release of the linux-next tree
(usually sometime within the next 24 hours during the week.)
The patch will hopefully also be merged in Linus's tree for the
next -rc kernel release.
If you have any questions about this process, please let me know.

Subject: staging: comedi: ni_daq_700: fix dio subdevice regression
Here is a small patch to fix a problem caused by a previous patch that
removed the callback function. The callback remove patch:
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=1de02225358988e8fd48d1dc3fd12336bbae258a
I finally booted my dev machine on the latest kernel (running Debian
here so it's still on 3.2 normally) to test the ni_daq_700 driver with
my test program and noticed this bug.
Shift the DIO_R read result to bits 8..15 Digital direction
configuration: channels 0-7 output, 8-15 input (8225 device emu as port
A output, port B input, port C N/A).
