From f570e1dd8469d39420f406a4f5442c270b1e759e Mon Sep 17 00:00:00 2001 From: Tracey Dent Date: Sun, 7 Nov 2010 09:43:33 -0500 Subject: EDAC: Remove deprecated kbuild goal definitions Change EDAC's Makefile to use -y instead of -objs because -objs is deprecated and not mentioned in Documentation/kbuild/makefiles.txt.

Normally, when we remove a polling low-level driver, we go and cancel all the queued work. However, the workqueue unreg happens based on the ->op_state setting, and edac_mc_del_mc() sets this to OP_OFFLINE _before_ we cancel the work item, leading to NULL ptr oops on the workqueue list. Fix it by putting the unreg stuff in proper order.

Thus, when we early-exit, we need to reverse the compound logic statement properly.
