dmaengine: mic_x100_dma: use devm_kzalloc to fix an issue ...
The following patch introduced an issue.
commit f6206f00d8c5 ("dmaengine: mic_x100_dma: use the new helper to simplify the code")
This issue is :
kfree(mic_dma_dev)
.....
dma_async_device_unregister(mic_dma_dev->device);
Free the memory, and use it again.
So use devm_kzalloc to allocate mic_dma_dev to fix it.
When the Devres try to release the resources, it will call release at the
following order:
dma_async_device_unregister(mic_dma_dev->device);
.....
kfree(mic_dma_dev)
