[PATCH 4.19 043/149] scsi: 53c700: pass correct "dev" to dma_alloc_attrs()

[Greg Kroah-Hartman]

4.19-stable review patch.  If anyone has any objections, please let me know.

------------------

[ Upstream commit 8437fcf14deed67e5ad90b5e8abf62fb20f30881 ]

The "hostdata->dev" pointer is NULL here.  We set "hostdata->dev = dev;"
later in the function and we also use "hostdata->dev" when we call
dma_free_attrs() in NCR_700_release().

This bug predates git version control.
