[PATCH] usb: xhci: tegra: Fix runtime PM support

From: Jon Hunter <jonathanh@nvidia.com>
Date: 2018-05-30 15:12:04
Also in: linux-usb, lkml
Subsystem: the rest, usb subsystem, usb xhci driver · Maintainers: Linus Torvalds, Greg Kroah-Hartman, Mathias Nyman

Fix silly mistake when enabling runtime PM support for the Tegra XHCI
driver. If runtime PM was enabled correctly for the XHCI device, then
we should call pm_runtime_get_sync() to enable the device.

Fixes: ee9e5f4c7825 ("usb: xhci: tegra: Add runtime PM support")
