Subject: Re: [PATCH v1 5/5] scsi: ufs: UFS Host Performance Booster(HPB)
driver
Hi,
Thank you for the patch! Yet something to improve:
[auto build test ERROR on mkp-scsi/for-next]
[also build test ERROR on scsi/for-next next-20200320]
[cannot apply to v5.6-rc6]
[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]
