This series fixes two resource leaks in the cadence-quadspi driver's
probe error path and remove callback.

Patch 1 fixes an imbalanced pm_runtime_enable()/pm_runtime_disable()
pair: when probe defers after cqspi_request_mmap_dma(),
pm_runtime_disable() is called without a prior pm_runtime_enable().
It also adds the missing pm_runtime_dont_use_autosuspend() in both
the probe error path and the remove callback and a missing
pm_runtime_put_noidle() in the probe error path. This consolidates
fixes from upstream commits 5ff4d5d1af0c and 5e8bb0cc72f1.

Patch 2 fixes a DMA channel leak: when spi_register_controller() fails,
the channel acquired via cqspi_request_mmap_dma() is never released.
A dedicated error label is added to release it before the runtime PM
teardown. This fix is one part of upstream commit f18c8cfa4f1a.

This doesn't apply against current code, please check and resend.

That's v6.12, that's rather ancient...

This series is meant to be applied only on the stable trees, as there
was a backport there that broke probing in certain scenarios. I should
have mentioned this more clearly in the cover letter, apologies for the
noise. If I need to resend explicitly mentioning which stable trees this
patch should be applied to let me know and I'll happily do it.

Please do, as I'm confused :)
