From c1e8d29df04c08ff2231013c85bfb951bd562115 Mon Sep 17 00:00:00 2001 From: Ran Wang Date: Fri, 6 Mar 2020 17:23:28 +0800 Subject: usb: host: xhci-plat: add a shutdown commit b433e340e7565110b0ce9ca4b3e26f4b97a1decf upstream. When loading new kernel via kexec, we need to shutdown host controller to avoid any un-expected memory accessing during new kernel boot.
