[PATCH 7/7] ktest: Remove indexes from warnings check

From: Steven Rostedt
Date: Tue Feb 19 2013 - 23:09:54 EST


From: "Steven Rostedt (Red Hat)" <rostedt@xxxxxxxxxxx>

The index of a line where a warning is tested can be returned
differently on different versions of gcc (or same version compiled
differently). That is, a tab + space can give different results. This
causes the warning check to produce a false positive. Removing the
index from the check fixes this issue.
