Subject: [PATCH] tools: gpio: replace strncpy with strscpy
Date: Mon, 4 May 2026 21:52:51 +0200 [thread overview]
Message-ID: <20260504195251.53771-1-lucasp.linux@gmail.com> (raw)
Replace strncpy with strscpy in gpio-utils.c. strscpy is the preferred
way to copy strings in the kernel as it guarantees NUL-termination and
is more robust.
Reported by checkpatch.pl.
