Re: [PATCH] dmaengine: switchtec-dma: fix FIELD_GET misuse when programming SE threshold

Hi Vinod,
Following up on this one-line fix. The bug is still present in
linux-next as of next-20260521 at drivers/dma/switchtec_dma.c:1102 â??
FIELD_GET extracts a zero from the 9-bit thresh value against the
bits 23-31 mask, so the SE threshold field is never actually written.
