Subject: [PATCH 5.15 739/917] dmaengine: tegra210-adma: fix pm runtime unbalance

From: Dongliang Mu <mudongliangabcd@...il.com>

[ Upstream commit c5a51fc89c0103c03b8a54cf12dac7d014b3a2bf ]

The previous commit 059e969c2a7d ("dmaengine: tegra210-adma: Using
pm_runtime_resume_and_get to replace open coding") forgets to replace
the pm_runtime_get_sync in the tegra_adma_probe, but removes the
pm_runtime_put_noidle.

Fix this by continuing to replace pm_runtime_get_sync with
pm_runtime_resume_and_get in tegra_adma_probe.

Fixes: 059e969c2a7d ("dmaengine: tegra210-adma: Using pm_runtime_resume_and_get to replace open coding")
