Subject: [PATCH] selftests/proc: Fix string literal warning in proc-maps-race.c
This change resolves non literal string format warning invoked
for proc-maps-race.c while compiling.
proc-maps-race.c:205:17: warning: format not a string literal and no format arguments [-Wformat-security]
205 | printf(text);
| ^~~~~~
proc-maps-race.c:209:17: warning: format not a string literal and no format arguments [-Wformat-security]
209 | printf(text);
| ^~~~~~
proc-maps-race.c: In function ‘print_last_lines’:
proc-maps-race.c:224:9: warning: format not a string literal and no format arguments [-Wformat-security]
224 | printf(start);
| ^~~~~~
Added string format specifier %s for the printf calls
in both print_first_lines() and print_last_lines() thus
resolving the warnings invoked.
The test executes fine after this change thus causing no
affect to the functional behavior of the test.
