Subject: [PATCH v1 2/3] genetlink: Use string_is_valid() helper
Date: Fri, 3 Feb 2023 16:05:00 +0200 [thread overview]
Message-ID: <20230203140501.67659-2-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <20230203140501.67659-1-andriy.shevchenko@linux.intel.com>
Use string_is_valid() helper instead of cpecific memchr() call.
This shows better the intention of the call.
