[PATCH 5.1 22/46] net: seeq: fix crash caused by not set dev.parent

From: Greg Kroah-Hartman

[ Upstream commit 5afcd14cfc7fed1bcc8abcee2cef82732772bfc2 ]

The old MIPS implementation of dma_cache_sync() didn't use the dev argument,
but commit c9eb6172c328 ("dma-mapping: turn dma_cache_sync into a
dma_map_ops method") changed that, so we now need to set dev.parent.
