Subject: Remove stray syscall result reading code on syscall entry for s390
X-Git-Tag: v4.8~171
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=ab2f40224279861110114cad81fedadd7abe9b98;p=strace

Remove stray syscall result reading code on syscall entry for s390

This is a leftover from sysenter/sysexit split.
I can't run-test it, but from code inspection it seems to be correct.

* syscall.c (get_scno): Remove stray syscall result reading for s390[x].
