[PATCH 3/6] usb: xhci: add missing pm_runtime_dont_use_autosuspend() calls

[Joshua Crofts]

The disable_runtime label in xhci_plat_probe() and xhci_plat_remove() both
call pm_runtime_disable() on error or device teardown, but don't call
pm_runtime_dont_use_autosuspend(), causing resource leaks.

Add the missing pm_runtime_dont_use_autosuspend().

Found using Coccinelle.
