select(1, &in, NULL, &in, NULL);

Subject: [PATCH] objtool, perf: Fix GCC 8 -Wrestrict error
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Starting with recent GCC 8 builds, objtool and perf fail to build with
the following error:
../str_error_r.c: In function 'str_error_r':
../str_error_r.c:25:3: error: passing argument 1 to restrict-qualified parameter aliases with argument 5 [-Werror=restrict]
snprintf(buf, buflen, "INTERNAL ERROR: strerror_r(%d, %p, %zd)=%d", errnum, buf, buflen, err);
The code seems harmless, but there's probably no benefit in printing the
'buf' pointer in this situation anyway, so just remove it to make GCC
happy.
