Subject: [PULL 08/22] dma: Have dma_buf_rw() take a void pointer
Date: Fri, 31 Dec 2021 01:55:32 +0100 [thread overview]
Message-ID: <20211231005546.723396-9-philmd@redhat.com> (raw)
In-Reply-To: <20211231005546.723396-1-philmd@redhat.com>
DMA operations are run on any kind of buffer, not arrays of
uint8_t. Convert dma_buf_rw() to take a void pointer argument
to save us pointless casts to uint8_t *.
