So I've pulled this, but I'm not entirely convinced some of this was a cleanup.

That gpio_sim_config_make_device_group() change is "interesting". Doing

return &no_free_ptr(dev)->group;

looks a bit crazy. My first reaction to it was 'that can't be right".
It _is_ right, but I'm not convinced that getting rid of one kfree()
call in the error path above it is worth that kind of semantic
complexity.

I guess we'll get more used to this - and it will look a bit less
crazy in the process - but I did want to just note that I'm not
entirely convinced we should encourage things like this.
