Subject: [PATCH] isci: Fix dma_unmap_sg() nents value
Date: Fri, 27 Jun 2025 16:24:47 +0200 [thread overview]
Message-ID: <20250627142451.241713-2-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: ddcc7e347a89 ("isci: fix dma_unmap_sg usage")
