Subject: Re: [PATCH v2 net-next 13/13] qed: FW 8.42.2.0 debug features
Hi Michal,
I love your patch! Perhaps something to improve:
[auto build test WARNING on net-next/master]
[also build test WARNING on linus/master v5.5 next-20200121]
[if your patch is applied to the wrong git tree, please drop us a note to help
improve the system. BTW, we also suggest to use '--base' option to specify the
base tree in git format-patch, please see https://stackoverflow.com/a/37406982]
