3.16.60-rc1 review patch. If anyone has any objections, please let me know.

From: Federico Cuello fedux@fedux.com.ar
commit 21493316a3c4598f308d5a9fa31cc74639c4caff upstream.
Currently it's not possible to set volume lower than 26% (it just mutes).
Also fixes this warning:
Warning! Unlikely big volume range (=9472), cval->res is probably wrong. [13] FU [PCM Playback Volume] ch = 2, val = -9473/-1/1
, and volume works fine for full range.
