Subject: [PATCH 2/2] mtd: mtdsuper: replace simple_strtoul with kstrtouint
Date: Fri, 10 Apr 2026 21:37:35 +0800 [thread overview]
Message-ID: <20260410133739.1632-2-hechushiguitu666@gmail.com> (raw)
In-Reply-To: <20260410133739.1632-1-hechushiguitu666@gmail.com>
Modernize string-to-number conversion in mtdsuper.c by replacing
simple_strtoul with kstrtouint. This change provides proper type safety
for MTD device numbers which are non-negative integers.
Using kstrtouint avoids unsigned long to int conversion and is more
appropriate for device indices. The debug output format specifier is
updated to %u for unsigned int.
