Subject: Re: [PATCH v5 3/3] misc/pvpanic: add PCI driver
Hi Mihai,
Thank you for the patch! Yet something to improve:
[auto build test ERROR on linux/master]
[also build test ERROR on linus/master v5.12-rc3 next-20210316]
[cannot apply to char-misc/char-misc-testing soc/for-next]
[If your patch is applied to the wrong git tree, kindly drop us a note.
