[BUG] Serial/dma stall/failure after "dmaengine: fsl-edma: extract common fsl-edma code (no changes in behavior intended)"

[Krzysztof Kozlowski <krzk@kernel.org>]

Hi,

The commit 6ad069123f03bebe4315dea13d44845854ca6043 ("dmaengine:
fsl-edma: extract common fsl-edma code (no changes in behavior
intended)"), even though marked as no changes in behavior intended...
make serial console with DMA broken after boot. The console just hangs
- is not responsive even to SysRq. Usually after finishing boot -
before or after login prompt. Sometimes login is allowed and then it
hangs during printing dmesg.

Board: Toradex Colibri VF50 (NXP VF500, Cortex A5, serial configured
with DMA) on Iris Carrier.

Defconfig and boot log attached. I could not find any obvious error in boot log.

Let me know if you need more data.

Best regards,
Krzysztof
