edb34a4dbd Remove stale "depends on NETDEV_1000"in staging drivers
Mark Einon points out that the Kconfig option for NETDEV_1000 no longer
exists, and the merge of the staging drivers should have removed that
for the et131x driver.

And while checking for it, I noticed that slicoss had the same stale
dependency.  Remove that one too.

43a3beb6da Merge branch 'staging-next' into Linux 3.1
This was done to resolve a conflict in the
drivers/staging/comedi/drivers/ni_labpc.c file that resolved a build
bugfix in Linus's tree with a "better" bugfix that was in the
staging-next tree that resolved the issue in a more complete manner.

2d0c64ad04 staging: et131x: Move function declarations from et131x.h to et131x.c
The function declarations in et131x.h are no longer used now all
functions are in one file. Removed declarations from et131x.h and
added any required forward declarations to et131x.c.

cd8eca6f77 staging:iio:dac:ad5686: Check for negative values
Currently it is possible to write negative values to the ad5686's raw attribute.
This will cause undefined behaviour, so reject negative values.

Scale is currently reported in volts instead of millivolts. This patch fixes it.

9dc9961dca staging:iio:dac:ad5791: Allow asymmetrical reference voltages
The ad5791 currently assumes that the negative and positive supply have the
same absolute value, which is not necessarily true. This patch introduces a
offset attribute which will contain the negative supply voltage scaled
according to the iio spec. The raw attribute now accepts values in the range
of 0 to max instead of -max/2 to max/2.

While we are at it also fix the vref span calculation. Since both positive and
negative reference voltages are specificed as absolute values we need to add
them and not subtract them to get the reference voltage span.
