Subject: init: Replace simple_strtoul() with kstrtouint() in root_delay_setup()
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=a6446829f841bf108fca8ca1e8f4f67b3a59d86c;p=thirdparty%2Flinux.git

init: Replace simple_strtoul() with kstrtouint() in root_delay_setup()

Replace deprecated simple_strtoul() with kstrtouint() for better error
handling and input validation. Return 0 on parsing failure to indicate
invalid parameter, maintaining existing behavior for valid inputs.

The simple_strtoul() function is deprecated in favor of kstrtoint()
family functions which provide better error handling and are recommended
for new code and replacements.
