Subject: Re: [PATCH v2] remoteproc: Introduce prepare/unprepare ops for rproc
coredump
Hi Sibi,
Thank you for the patch! Yet something to improve:
[auto build test ERROR on v4.17-rc6]
[also build test ERROR on next-20180517]
[cannot apply to remoteproc/for-next]
[if your patch is applied to the wrong git tree, please drop us a note to help improve the system]
