From 83eb1a415023e6489bf5adb467f20156722172f0 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Wed, 26 Jun 2019 13:06:58 +0300 Subject: [PATCH] s390/dasd: Fix a precision vs width bug in dasd_feature_list() The "len" variable is the length of the option up to the next option or to the end of the string which ever first. We want to print the invalid option so we want precision "%.*s" but the format is width "%*s" so it prints up to the end of the string.
