Message

This patch set adds scale info to ad2s90's single channel, improve
error handling in it's functions and fix a possible race condition
issue.

The goal with this patch set is to address the points discussed in the
mailing list in an effort to move ad2s90.c out of staging.

Changes in v3:
 - Removed unconnected change in patch 1 (whitespace tidying up).
 - Added comment to patch 2's description regarding a code block that
was moved in patch 4.
 - Corrected scale in patch 5, from 2Pi/(2^12 - 1) to 2Pi/2^12 and
using IIO_VAL_FRACTIONAL_LOG2.

Changes in v2:
 - Added my S-o-B in patch 5.
