Subject: [PATCH] mmc: mvsdio: Fix dma_unmap_sg() nents value
Date: Tue, 26 Aug 2025 09:58:08 +0200 [thread overview]
Message-ID: <20250826075812.82305-2-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: 236caa7cc351 ("mmc: SDIO driver for Marvell SoCs")
