[ 01/48] staging:iio:ad7606: Re-add missing scale attribute

[Ben Hutchings]

3.2-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Lars-Peter Clausen <lars@xxxxxxxxxx>

commit 279bf2e57c30c9a4482b2b6ede11b31c41e35e78 upstream.

Commit 50ac23be ("staging:iio:adc:ad7606 add local define for chan_spec
structures.") accidentally removed the scale info_mask flag. This patch
adds it back again.

[bwh: Backported to 3.2:
 - info_mask was completely gone rather than set to another flag
 - IIO_CHAN_INFO_SCALE_SHARED_BIT was not defined; write it out as a shift]
