zhangqilong 6db4896608 dmaengine: mediatek:Fix PM usage reference leak of mtk_uart_apdma_alloc_chan_resources ... [ Upstream commit 545b2baac8 ] 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: 1) Replacing it with pm_runtime_resume_and_get to keep usage counter balanced. 2) Add putting operation before returning error.
