Subject: [PATCH] mmc: loongson2-mmc: drop redundant memset after dma_alloc_coherent()
Date: Thu, 29 Jan 2026 00:59:17 -0300 [thread overview]
Message-ID: <20260129035917.48080-1-andre.korol.dev@gmail.com> (raw)
dma_alloc_coherent() returns zeroed memory, so the memset() immediately
after allocation is redundant.
