Fixed pep8/flake8 python style code for lsvmbus tool. The TAB indentation was on purpose ignored (pep8 rule W191) to make sure the code is complying with the Linux code guideline. The following command doe not show any warnings now: pep8 --ignore=W191 lsvmbus flake8 --ignore=W191 lsvmbus Signed-off-by: Adrian Vladu <avladu@cloudbasesolutions.com> Cc: "K. Y.
