spi: qup: fix error pointer deref after DMA setup failure

2026-06-19T11:21:46+00:00

[ Upstream commit a7e8f3efd50a165ba0189f6dc57f7e51a7d149db ] The driver falls back to PIO mode if DMA setup fails during probe. Make sure to the clear the DMA channel pointers on setup failure to avoid dereferencing an error pointer (or attempting to release a channel a second time) on later probe errors or driver unbind. This issue was flagged by Sashiko when reviewing a devres allocation conversion patch.
