From: Dave Peterson Date: Sun, 26 Mar 2006 09:38:44 +0000 (-0800) Subject: [PATCH] EDAC: i82875p cleanup X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=637beb697b8dc7b9d7a35c2b6488332e77963ded;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git [PATCH] EDAC: i82875p cleanup - Fix i82875p_probe1() so it calls pci_get_device() instead of pci_find_device(). - Fix i82875p_probe1() so it cleans up properly on failure. - Fix i82875p_init() so it cleans up properly on failure.
