Subject: [PATCH] crypto: img-hash: Fix dma_unmap_sg() nents value
Date: Mon, 30 Jun 2025 11:16:22 +0200 [thread overview]
Message-ID: <20250630091623.75655-2-fourier.thomas@gmail.com> (raw)
The dma_unmap_sg() functions should be called with the same nents as the
dma_map_sg(), not the value the map function returned.
Fixes: d358f1abbf71 ("crypto: img-hash - Add Imagination Technologies hw hash accelerator")
