Merge tag 'dev_groups_all_drivers' into fpga-dfl-for-5.4
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:
https://lore.kernel.org/r/20190731124349.4474-2-gregkh@linuxfoundation.org
for details on this patch, and examples of how to use it in other
drivers.
