[PATCH 4.14 087/165] staging: fsl-dpaa2/eth: Fix incorrect casts

[Greg Kroah-Hartman]

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

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

From: Ioana Radulescu <ruxandra.radulescu@xxxxxxx>

[ Upstream commit 75c583ab9709692a60871d4719006391cde8dc1d ]

The DPAA2 Ethernet driver incorrectly assumes virtual addresses
are always 64b long, which causes compiler errors when building
for a 32b platform.

Fix this by using explicit casts to uintptr_t where necessary.
