From 62733e5a5a480a893e56fa6133ae90904d857bc4 Mon Sep 17 00:00:00 2001 From: Heiko Carstens Date: Fri, 11 Sep 2009 10:28:15 +0200 Subject: [S390] cio: move scsw helper functions to header file All scsw helper functions are very short and usage of them shouldn't result in function calls. Therefore we move them to a separate header file. Also saves a lot of EXPORT_SYMBOLs.
