I have now done this with patch 1/10.  Here's the pull info if any
subsystem maintainer wants to suck this into their tree to provide the
ability for drivers to add/remove attribute groups easily.

This is part of my driver-core tree now, and will go to Linus for
5.4-rc1, along with a few platform drivers that have been acked by their
various subsystem maintainers that convert them to use this new
functionality.

If anyone has any questions about this, please let me know.

thanks,

greg k-h

  driver core: add dev_groups to all drivers (2019-08-02 12:37:53 +0200)

----------------------------------------------------------------
dev_groups added to struct driver

Persistent tag for others to pull this branch from

This is the first patch in a longer series that adds the ability for the
driver core to create and remove a list of attribute groups
automatically when the device is bound/unbound from a specific driver.

See:

for details on this patch, and examples of how to use it in other
drivers.

Was planning to re-spin DRM a series which uses .dev_groups, although
I cannot see the core patch.
Did the it get reverted or simply fell though the cracks?

Nope, it's in there:
        23b6904442d0 ("driver core: add dev_groups to all drivers")
which showed up in the 5.4 kernel release.

Lots of other subsystems have already been converted to use this, do you
not see it in your tree?

A case of PEBKAC it seems - I was looking at a 5.3 checkout somehow.

Thanks for the core work. Will check/merge the fbdev patches over the
next few days and polish drm land.
