3.4-stable review patch. If anyone has any objections, please let me know.
------------------ From: Mark Cave-Ayland <[email protected]> commit 9473ca6e920a3b9ca902753ce52833657f9221cc upstream. An error in calculating the offset in an skb causes the driver to read essential device info from the wrong locations. The main effect is that automatic gain calculations are nonsense.
