6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Christophe JAILLET christophe.jaillet@wanadoo.fr
commit 21553258b94861a73d7f2cf15469d69240e1170d upstream.
If an error occurs after a successful mfd_add_devices() call, it should be undone by a corresponding mfd_remove_devices() call, as already done in the remove function.
