Subject: b43legacy: replace simple_strtol() with kstrtoint()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=871b4b48cdbfe4fb7f687801fc265619b35cf476;p=linux.git

b43legacy: replace simple_strtol() with kstrtoint()

The simple_strtol() function is deprecated since it does not
check for the range overflow. Use kstrtoint() instead.
