[PATCH 0/2] dmaengine: qcom: bam_dma: Fixes for unbind

[Mostafa Saleh]

On Lenovo Mini-x Gen 10 (X1P42100 based) I am using VFIO-platform
to assing the QCE/BAM to VMs.

During unbind:
echo 1dc4000.dma-controller > /sys/bus/platform/drivers/bam-dma-engine/unbind
echo 1dfa000.crypto > /sys/bus/platform/drivers/qcrypto/unbind

I see a system reset quite often, looking more into this,
that seems to be related to runtime PM, with those fixes I don't
see that anymore.

This patches apply on linux-next.

  dmaengine: qcom: bam_dma: Take a PM ref at remove()
  dmaengine: qcom: bam_dma: Do not touch remote BAM in remove()
