[PATCH 1/1] dmaengine: mediatek-cqdma: fix wrong register usage in mtk_cqdma_start

[shun-chih.yu]

From: Shun-Chih Yu <shun-chih.yu@mediatek.com>

This patch fixes wrong register usage in the mtk_cqdma_start. The
destination register should be MTK_CQDMA_DST2 instead.

Fixes: b1f01e48df5a ("dmaengine: mediatek: Add MediaTek Command-Queue DMA controller for MT6765 SoC")
