Re: [PATCH v1 2/2] usb: phy: Add USB3 PHY support for Intel LGM SoC

[kernel test robot <lkp@xxxxxxxxx>]

Hi "Ramuthevar,Vadivel,

Thank you for the patch! Perhaps something to improve:

[auto build test WARNING on balbi-usb/testing/next]
[also build test WARNING on usb/usb-testing linus/master v5.7 next-20200608]
[cannot apply to linux/master]
[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]
