Subject: x86: remove unneeded check in mmconf reject
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=d2ebdf4bae4f1d7c30e71fd74f270ca4cda024fc;p=deliverable%2Flinux.git

x86: remove unneeded check in mmconf reject

mmconfig is only used to access extended configuration space.

so don't need to reject MFG that only have one entry and only handle bus0.
