[PATCH v2 05/13] dmaengine: at_xdmac: Print debug message after realeasing the lock
From: Tudor Ambarus <hidden>
Date: 2021-11-25 09:03:04
Also in:
dmaengine, linux-serial, lkml
Subsystem:
dma generic offload engine subsystem, microchip at91 dma drivers, the rest · Maintainers:
Vinod Koul, Ludovic Desroches, Linus Torvalds
It is desirable to do the prints without the lock held if possible.
