Commit 157ae5ffd76a dmaengine: mediatek: Fix a possible deadlock error
in mtk_cqdma_tx_status() fixed locks but kept unused varibale leading to
warning and build failure (due to warning treated as errors)
drivers/dma/mediatek/mtk-cqdma.c: In function 'mtk_cqdma_find_active_desc':
drivers/dma/mediatek/mtk-cqdma.c:423:23: error: unused variable 'flags' [-Werror=unused-variable]
423 | unsigned long flags;
| ^~~~~
