| Subject: usb: core: Add PM runtime calls to usb_hcd_platform_shutdown |
| |
| [ Upstream commit 8ead7e817224d7832fe51a19783cb8fcadc79467 ] |
| |
| 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. |
