Subject: Re: [PATCH v2 3/8] partitions: Introduce NVIDIA Tegra Partition Table

Hi Dmitry,

I love your patch! Yet something to improve:

[auto build test ERROR on tegra/for-next]
[also build test ERROR on block/for-next linus/master v5.6-rc4 next-20200306]
[cannot apply to ulf.hansson-mmc/next]
[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]
