tools/thermal/tmon: Fix string truncation warning in optarg copy
GCC warns about possible string truncation with -Wstringop-truncation:
tmon.c: In function ‘main’:
tmon.c:233:25: warning: ‘__builtin_strncpy’ specified bound 20 equals
destination size [-Wstringop-truncation]
233 | strncpy(ctrl_cdev, optarg,
CDEV_NAME_SIZE);
|
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Replace strncpy() with snprintf() to guarantee NUL-termination and
silence the compiler warning.
Fixes: 94f69966faf8 ("tools/thermal: Introduce tmon, a tool for thermal subsystem")
