[PATCHv2 0/9] dma: mv_xor: convert to devm resource management

[Rosen Penev <rosenp@gmail.com>]

Convert the mv_xor driver to use managed device resources (devm)
to simplify error handling and removal paths.

Patch 5 replaces the open-coded clock acquire/enable/disable/put
with devm_clk_get_optional_enabled, eliminating manual clock
cleanup in the probe error path.

Patch 6 adds the missing platform remove callback so that
channels, DMA devices, and IRQs are properly cleaned up on
driver unbind.

Patch 7 converts DMA pool allocation and IRQ requests to their
devm counterparts, allowing removal of the err_free_irq and
err_free_dma error labels.

v2: add more sashiko fixes.

Rosen Penev (9):
  dmaengine: mv_xor: initialize chan state before requesting IRQ
  dmaengine: mv_xor: fix use-after-free in probe error path
  dmaengine: mv_xor: bound maximum channels for Armada 37xx
  dmaengine: mv_xor: abort channel before freeing resources on timeout
  dmaengine: mv_xor: use devm_clk_get_optional_enabled
  dmaengine: mv_xor: switch to of_irq_get()
  dmaengine: mv_xor: use devm for dma pool and irq
  dmaengine: mv_xor: allocate dummy buffers with dmam_alloc_coherent
  dmaengine: mv_xor: add missing platform remove function
