This reverts commit 270dac35c26433d06a89150c51e75ca0181ca7e4. The commits causes command timeouts on AC plug/unplug. It isn't yet clear why. As the commit was for a single rather obscure controller, revert the change for now. The problem was reported and bisected by Gu Rui in bug#34692. https://bugzilla.kernel.org/show_bug.cgi?id=34692 Also, reported by Rafael and Michael in the following thread. http://thread.gmane.org/gmane.linux.kernel/1138771 Signed-off-by: Tejun Heo <tj@kernel.org> Reported-by: Gu Rui <chaos.proton@gmail.com> Reported-by: Rafael J.
