Subject: [PATCH 1/8] usb: ohci-hcd: Do not zero out DMA coherent memory
Date: Mon, 27 May 2019 11:14:53 -0700 [thread overview]
Message-ID: <20190527181500.17456-1-andrew.smirnov@gmail.com> (raw)
Memory returned by dma_alloc_coherent() should already be zeroed
out, so there's no need to do this explicitly.
