Subject: [PATCH] devlink/param: replace deprecated strcpy() with strscpy()
Date: Wed, 6 May 2026 18:14:11 -0300 [thread overview]
Message-ID: <20260506211415.16343-1-alvaroc.dev@gmail.com> (raw)
Replace strcpy() call used to extract a string parameter from param_data
with strscpy(). Since strscpy() already performs bounds checking and
ensures the destination string is NUL-terminated, remove the string
length check as well.
