Subject: usb: xhci: tegra: Fix runtime PM support
Date: Wed, 30 May 2018 16:11:42 +0100 [thread overview]
Message-ID: <1527693102-4711-1-git-send-email-jonathanh@nvidia.com> (raw)
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")
