From: Thomas Fourier Date: Tue, 26 Aug 2025 07:58:08 +0000 (+0200) Subject: mmc: mvsdio: Fix dma_unmap_sg() nents value X-Git-Tag: v6.12.49~49 X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=bd5524ec715510b681de1f14de423c6d7aad2759;p=thirdparty%2Fkernel%2Fstable.git mmc: mvsdio: Fix dma_unmap_sg() nents value commit 8ab2f1c35669bff7d7ed1bb16bf5cc989b3e2e17 upstream. The dma_unmap_sg() functions should be called with the same nents as the dma_map_sg(), not the value the map function returned.
