Subject: [PATCH] spi: core: add dma_map_dev for __spi_unmap_msg()
Date: Wed,  6 Apr 2022 18:52:38 +0530	[thread overview]
Message-ID: <20220406132238.1029249-1-vkoul@kernel.org> (raw)

Commit b470e10eb43f ("spi: core: add dma_map_dev for dma device") added
dma_map_dev for _spi_map_msg() but missed to add for unmap routine,
__spi_unmap_msg(), so add it now.

Fixes: b470e10eb43f ("spi: core: add dma_map_dev for dma device")
Cc: stable@vger.kernel.org # v5.14+
