Subject: s390/cio: move struct node_descriptor to cio.h
X-Git-Tag: v5.4-rc1~692^2~18
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=96e5aaf914060a02955b09487e176769a75ae225;p=platform%2Fkernel%2Flinux-rpi.git

s390/cio: move struct node_descriptor to cio.h

This allows device drivers (eg. qeth) to use the struct when processing
information retrieved via RCD.
