From 749ede57443b2a7ede2db105145f21047efcea6a Mon Sep 17 00:00:00 2001 From: Dave Peterson Date: Sun, 26 Mar 2006 01:38:45 -0800 Subject: [PATCH] [PATCH] EDAC: cleanup code for clearing initial errors Fix xxx_probe1() functions so they call xxx_get_error_info() functions to clear initial errors. This is simpler and cleaner than duplicating the low-level code for accessing PCI config space. Signed-off-by: David S.
