Pull driver core changes from Greg KH:
 "Here is the small set of driver core and debugfs updates for 5.14-rc1.

  Included in here are:

   - debugfs api cleanups (touched some drivers)

   - devres updates

   - tiny driver core updates and tweaks

  Nothing major in here at all, and all have been in linux-next for a
  while with no reported issues"

Pull dmaengine updates from Vinod Koul:
 "This time around we have a smaller pull request than usual and this
  includes code removal, so should be good!

  New drivers/devices
   - Support for QCOM SM8250 GPI DMA
   - removal of shdma-of driver and binding

  Updates:
   - arm-pl08x yaml binding move
   - altera-msgdma gained DT support
   - removal of imx-sdma platform data support
   - idxd and xilinx driver updates"

* tag 'dmaengine-5.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/vkoul/dmaengine: (22 commits)
  dmaengine: imx-sdma: Remove platform data header
  dmaengine: xilinx: dpdma: Fix spacing around addr[i-1]
  dmaengine: xilinx: dpdma: Use kernel type u32 over uint32_t

  dmaengine: xilinx: dpdma: Print channel number in kernel log messages
  dt-bindings: dma: convert arm-pl08x to yaml
  dmaengine: idxd: remove devm allocation for idxd->int_handles
  ...

Since commit 6c5f05a6cd88 ("ARM: imx3: Remove imx3 soc_init()")
there are no more users of struct sdma_script_start_addrs outside
of the driver itself, thus let's move the struct declaration just
to the driver source code and remove the header file as unused one.
