From: Christophe JAILLET <christophe.jail...@wanadoo.fr> commit 320bdbd816156f9ca07e5fed7bfb449f2908dda7 upstream.
When a list is completely iterated with 'list_for_each_entry(x, ...)', x is not NULL at the end. While at it, remove a useless initialization of the ndev variable. It is overridden by 'list_for_each_entry'. Fixes: f2663872f073 ("crypto: cavium - Register the CNN55XX supported crypto algorithms.")
