Revert "usb: gadget: udc-xilinx: replace memcpy with memcpy_toio"
This reverts commit 8cb339f1c1f04baede9d54c1e40ac96247a6393b as it throws up a bunch of sparse warnings as reported by the kernel test robot. Reported-by: kernel test robot <lkp@intel.com> Link: https://lore.kernel.org/r/202209020044.CX2PfZzM-lkp@intel.com Fixes: 8cb339f1c1f0 ("usb: gadget: udc-xilinx: replace memcpy with memcpy_toio") Cc: stable@vger.kernel.org Cc: Linus Walleij <linus.walleij@linaro.org> Cc: Piyush Mehta <piyush.mehta@amd.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
