Subject: [PATCH 3/5] spi: tle62x0: Use kstrtoul() instead of simple_strtoul()
Date: Fri, 9 Oct 2026 19:06:07 +0530 [thread overview]
Message-ID: <20261009133609.579046-4-code@aayushk.dev> (raw)
In-Reply-To: <20261009133609.579046-1-code@aayushk.dev>
Use the recommended kstrtoul() instead of the deprecated
simple_strtoul(). Check the return value and reject invalid values.
