Since you already have "qcom" as the parent directory name, I don't know how
adding "qcom" prefix for the drivers in child directory helps. It is required
for the module name but not for the driver name.

If you look at current qcom soc drivers, then most of them are without prefix
but _some_ are with prefix. And the later ones doesn't make sense to me,

But I'll leave it to Bjorn to take the call.
