This patch is relative to linux-next repository tag next-20140206
The bug that this patch fixes affects only the DA9052 ONKEY driver.
The problem was detected whilst running a scripted set of functional
regression tests whilst investigating a different problem.
This patch has been test compiled on an amd64 server for both x86
and arm targets.
This patch has been spot verified using an SMDK6410 platform
fly-wired to a Dialog da9053 EVB.
