From 9ff91a33c082c6163119aff659aaa20399178c5b Mon Sep 17 00:00:00 2001
From: Heiko Carstens <hca@linux.ibm.com>
Date: Thu, 7 Mar 2024 13:28:15 +0100
Subject: s390/cio: use new address translation helpers

Use virt_to_dma32() and friends to properly convert virtual to physical and
physical to virtual addresses so that "make C=1" does not generate any
warnings anymore.
