Subject: [PATCH] USB: dwc3: fix runtime pm imbalance on unbind
Git-commit: 44d257e9012ee8040e41d224d0e5bfb5ef5427ea
References: git-fixes
Patch-mainline: v6.4-rc1

Make sure to balance the runtime PM usage count on driver unbind by
adding back the pm_runtime_allow() call that had been erroneously
removed.

Fixes: 266d0493900a ("usb: dwc3: core: don't trigger runtime pm when remove driver")
