[PATCH 5.17 009/225] usb: xhci: tegra:Fix PM usage reference leak of tegra_xusb_unpowergate_partitions

[Greg Kroah-Hartman]

From: zhangqilong <zhangqilong3@xxxxxxxxxx>

commit 8771039482d965bdc8cefd972bcabac2b76944a8 upstream.

pm_runtime_get_sync will increment pm usage counter
even it failed. Forgetting to putting operation will
result in reference leak here. We fix it by replacing
it with pm_runtime_resume_and_get to keep usage counter
balanced.
