[PATCH -next] perf tests: Fix an incorrect type in append_script()
From: Jiapeng Chong
Date: Fri Nov 15 2024 - 04:15:52 EST
The return value from the call to readlink() is ssize_t. However, the
return value is being assigned to an size_t variable 'len', so making
'len' an ssize_t.
./tools/perf/tests/tests-scripts.c:182:5-8: WARNING: Unsigned expression compared with zero: len < 0.
