Hello,

This series fixes some problems that I spotted recently, secondly the
driver's code gets a cleanup. Please review and apply, thanks in advance!

Changelog:

v4: - Addressed Jon's request to *not* remove the runtime PM usage, instead
      there is now new patch that makes RPM more practical:

        dmaengine: tegra-apb: Keep clock enabled only during of DMA transfer

    - Added new minor patch to clean up RPM's teardown:

        dmaengine: tegra-apb: Clean up runtime PM teardown

v3: - In the review comment to v1 Michał Mirosław suggested that "Prevent
      race conditions on channel's freeing" does changes that deserve to
      be separated into two patches. I factored out and improved tasklet
      releasing into this new patch:

        dmaengine: tegra-apb: Clean up tasklet releasing

    - The "Fix use-after-free" patch got an improved commit message.

v2: - I took another look at the driver and spotted few more things that
      could be improved, which resulted in these new patches:

        dmaengine: tegra-apb: Remove runtime PM usage
        dmaengine: tegra-apb: Clean up suspend-resume
        dmaengine: tegra-apb: Add missing of_dma_controller_free
        dmaengine: tegra-apb: Allow to compile as a loadable kernel module
        dmaengine: tegra-apb: Remove MODULE_ALIAS
