From 18d00acfe2f3fc5ee62f679eb2e397ae962fe69b Mon Sep 17 00:00:00 2001 From: Hendrik Brueckner Date: Fri, 11 Sep 2009 10:28:41 +0200 Subject: [PATCH] [S390] kernel: Convert upper case scpdata to lower case If the CP SET LOADDEV on the 3215 console has been used to specify SCPdata, all data is converted to upper case letters. When scpdata contains upper case letters only, convert all letters to lower case.
