Hi Geert,

Thank you for the patches.

I had patches similar to 3/4 and 4/4 in my tree, that's a sign you're going in 
the right direction (or at least the direction I consider to be right :-)). 
For the whole series,

One thing to consider is to add

#define pr_fmt(fmt) KBUILD_MODNAME ": " fmt

before any #include to make sure all messages
are appropriately prefixed by subsystem name.

One day, I'd very much like to avoid this
by making it the default.
