[PATCH 0/4] Add more devm_ functions to simplify probe path in drivers/spi/atmel-quadspi.c

[Bence Csókás]

The probe function of the atmel-quadspi
driver got quite convoluted, especially
since the addition of SAMA7G5 support,
that was forward-ported from an older
vendor kernel. To alleivate this - and
similar problems in the future - an
effort was made to migrate as many
functions as possible, to their devm_
managed counterparts. The few functions,
which did not yet have a devm_ variant,
are added in patch 1 and 2 of this series.
Patch 3 and 4 then use these APIs to
simplify and fix the probe() function.

Bence Csókás (4):
      dma: Add devm_dma_request_chan()
      pm: runtime: Add new devm functions
      spi: atmel-quadspi: Use `devm_dma_request_chan()`
      spi: atmel-quadspi: Fix unbalanced pm_runtime by using devm_ API
