From 101f6f4ba7109aafd7b3f2eafd7124f854dda451 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Wed, 20 Jun 2007 12:03:09 +0200 Subject: [ALSA] Fix unfreed pnp driver in opti9xx ISA driver - Added the missing pnp_unregister_card_driver() in the case ISA PnP isn't found, which caused an error at kobject_add with -EEXIST Jun 11 09:07:31 rain kernel: kobject_add failed for opti9xx with -EEXIST, don't try to register things with the same name in the same directory.

Now it behaves like the former version.
