Hi Pawel,

The Reported-by tag should be above your Sob tag, I will change it.
Except the patch reported build error by kernel test robot, I will apply
your other four patches after finishing the compile test.

Hi Peter,

I'm going to fix the "usb: cdns3: Adds missing __iomem markers" today.
I haven't seen any issue on ARCH=parisc. Maybe it's some specific riscv arch issue.

I believe that:
[auto build test WARNING on next-20201211]
[cannot apply to peter.chen-usb/ci-for-usb-next v5.10 v5.10-rc7 v5.10-rc6 v5.10]

is not the problem. I based on peter.chen-usb/for-usb-next.

Also I can't open the url from kernel test robot report.
Maybe there is some temporary issue with server.

Thanks,
Pawel
