Subject: Re: [PATCH v8 26/26] PCI: dwc: Add DW eDMA engine support
Hi Serge,
I love your patch! Perhaps something to improve:
[auto build test WARNING on helgaas-pci/next]
[also build test WARNING on linus/master next-20221220]
[cannot apply to vkoul-dmaengine/next helgaas-pci/for-linus v6.1]
[If your patch is applied to the wrong git tree, kindly drop us a note.
