[PATCH linux-next] tracing: move from strlcpy with unused retval to strscpy

[zhang.songyi]

From: zhang songyi <zhang.songyi@xxxxxxxxxx>

Follow the advice of the below link and prefer 'strscpy' in this
subsystem. That's now the recommended way to copy NUL terminated
strings. Conversion is 1:1 because the return value is not used.
