[PATCH for-6.14 v4 0/2] Add more devm_ functions to fix PM imbalance in spi/atmel-quadspi.c

[Bence Csókás <csokas.bence@xxxxxxxxx>]

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. During the port, a bug was introduced, where
the PM get() and put() calls were imbalanced. 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 of
this series. Patch 2 then uses these APIs to fix the probe() function.

Change in v4:
* the DMA cleanup was split out and will be submitted separately for 6.15
