Subject: Re: [PATCH v4 4/4] RISC-V: Implement new SBI v0.2 extensions
Hi Atish,
Thank you for the patch! Yet something to improve:
[auto build test ERROR on next-20191125]
[cannot apply to linus/master v5.4 v5.4-rc8 v5.4-rc7 v5.4]
[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]
