Subject: crypto: aspeed - Use memcpy_from_sglist() in aspeed_ahash_dma_prepare()
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=51d0f5020deeef1c678b7e3e71420b2842215662;p=thirdparty%2Flinux.git

crypto: aspeed - Use memcpy_from_sglist() in aspeed_ahash_dma_prepare()

Replace scatterwalk_map_and_copy() with memcpy_from_sglist() in
aspeed_ahash_dma_prepare(). The latter provides a simpler interface
without requiring a direction parameter, making the code easier to
read and less error-prone.

No functional change intended.
