From 3c52cc57ccd5c99441368d5e66be36681ce90e72 Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Sun, 24 Oct 2010 11:12:28 -0200 Subject: [PATCH] i7core_edac: properly terminate pci_dev_table At pci_xeon_fixup(), it waits for a null-terminated table, while at i7core_get_all_devices, it just do a for 0..ARRAY_SIZE. As other tables are zero-terminated, change it to be terminate with 0 as well, and fixes a bug where it may be running out of the table elements.
