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.
Change in v2: rebased onto Linus' master, which is:
commit bc8198dc7ebc ("Merge tag 'sched_ext-for-6.14' of
git://git.kernel.org/pub/scm/linux/kernel/git/tj/sched_ext")
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
