Subject: [PATCH] crypto: atmel - Fix dma_unmap_sg() direction
Date: Wed, 3 Sep 2025 10:34:46 +0200 [thread overview]
Message-ID: <20250903083448.621694-2-fourier.thomas@gmail.com> (raw)
It seems like everywhere in this file, dd->in_sg is mapped with
DMA_TO_DEVICE and dd->out_sg is mapped with DMA_FROM_DEVICE.
Fixes: 13802005d8f2 ("crypto: atmel - add Atmel DES/TDES driver")
Cc: <stable@vger.kernel.org>
