It is expected that visorbus_device_destroy will not be called on the
same visor_device again, or this would be a double free.

I'll take this, but you should get rid of it in the future.

It's not a "no device present" error, it's a "you gave me invalid data"

Too bad this is the wrong name :(
I'm not going to take this, sorry. Just drop silly things like this
from files, it means nothing to no one.

As this is kernel-doc format, the correct change should be:
/**
* struct visor_vbus_deviceinfo
right?
I'm dropping this.

If you are going to do kernel-doc, do it correctly please. Don't make
it half-way, that helps no one as a follow-on patch to do it correctly
is now required.
Please do it correct the first time.

So far these patches are pretty annoying. You seem to be using
Christmas tree ordering:
short
medium
loooooong
Instead of reverse Christmas tree:
loooooong
medium
short
Nobody else does that... People either use reverse Christmas tree or
they don't care. Also putting alloc functions in the declarations is a
common source of bugs. Empirically, from reviewing thousands of static
checker bugs, I can say that declarations get reviewed worse than normal
code.

dan carpenter

This goto is wrong. It calls parser_done(ctx) when it should just call
kfree(ctx). The difference is that parser_done() looks like this:
289 static void parser_done(struct parser_context *ctx)
290 {
291 chipset_dev->controlvm_payload_bytes_buffered -= ctx->param_bytes;
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
We never incremented this so we shouldn't be decrementing it.
292 kfree(ctx);
293 }

dan carpenter
