Subject: [PATCH 0/5] dma: don't set chancnt
Date: Tue, 14 Mar 2023 01:02:45 +0800	[thread overview]
Message-ID: <20230313170250.815-1-jszhang@kernel.org> (raw)

I'm patching dw-axi-dmac to add more features, but I found a small
clean up point and some drivers in drivers/dma/ have the same issue,
so this series comes.

The dma framework will calculate the dma channels chancnt, setting it
is wrong.

NOTE: I leav drivers/dma/ioat/ as is, because its logic have a
heavy dependency on chancnt usage, however it's still doable.
