[PATCH 0/7] Soundwire: clean up sysfs group creation

[Greg Kroah-Hartman]

Note, this is a redone version of a very old series I wrote back in
2022:
	https://lore.kernel.org/r/20220824135951.3604059-1-gregkh@xxxxxxxxxxxxxxxxxxx
but everyone has forgotten about it now, and I've reworked it, so I'm
considering it a "new" version, and not v2.

Here's a series that adds the functionality to the driver core to hide
entire attribute groups, in a much saner way than we have attempted in
the past (i.e. dynamically figuring it out.)  Many thanks to Dan for
this patch.  I'll also be taking this into my driver-core branch and
creating a stable tag for anyone else to pull from to get it into their
trees, as I think it will want to be in many for this development cycle.

After the driver core change, there's cleanups to the soundwire core for
how the attribute groups are created, to remove the "manual" creation of
them, and allow the driver core to create them correctly, as needed,
when needed, which makes things much smaller for the soundwire code to
manage.

Comments appreciated!

thanks,
