Subject: Re: [PATCH v2 2/3] efi: call get_event_log before ExitBootServices

Hi Thiebaud,

[auto build test ERROR on efi/next]
[also build test ERROR on next-20170913]
[cannot apply to char-misc/char-misc-testing linus/master v4.13]
[if your patch is applied to the wrong git tree, please drop us a note to help improve the system]

      It only hurts bisectibility.
