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

commit 0ba8da961bd868c67a8dae3dbbee145514515e9c upstream.
Currently driver reports device bandwidth list as available sampling frequency. But sampling frequency is actually twice the device bandwidth. This patch fixes this issue.
