6.18-stable review patch. If anyone has any objections, please let me know.

------------------

From: Aleksander Jan Bajkowski <olek2@wp.pl>

[ Upstream commit b6e32ba6d32503440a3e3e16c8d0521cbb7e0c5d ]

During driver detach, the same hash algorithm is unregistered multiple
times due to a wrong iterator.
