From 8ead7e817224d7832fe51a19783cb8fcadc79467 Mon Sep 17 00:00:00 2001 From: Tony Lindgren Date: Fri, 22 Mar 2019 14:54:05 -0700 Subject: usb: core: Add PM runtime calls to usb_hcd_platform_shutdown If ohci-platform is runtime suspended, we can currently get an "imprecise external abort" on reboot with ohci-platform loaded when PM runtime is implemented for the SoC. Let's fix this by adding PM runtime support to usb_hcd_platform_shutdown.
