Subject: s390/chsc: fix ioctl CHSC_INFO_CU command
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=6228c2a51edccf3e01fc4db065aac91b4cafdc76;p=linux-beck.git

s390/chsc: fix ioctl CHSC_INFO_CU command

Via CHSC_INFO_CU we ought to provide userspace with control unit
configuration data. Due to an erroneous request code we trigger the
wrong chsc command. Fix this copy and paste error.
