[PATCH v4 04/13] spi: airoha: remove unnecessary switch to non-dma mode

From: Mikhail Kshevetskiy <hidden>
Date: 2025-08-23 00:16:40
Also in: linux-spi, lkml
Subsystem: airoha spi snfi driver, spi subsystem, the rest · Maintainers: Lorenzo Bianconi, Ray Liu, Mark Brown, Linus Torvalds

The code switches to dma at the start of dirmap operation and returns
to non-dma at the end of dirmap operation, so an additional switch to
non-dma at the start of dirmap write is not required.
