Merge tag 'dev_groups_all_drivers' into driver-core-next
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.
