Subject: arch/x86/mm/kmemcheck/kmemcheck.c: use kstrtoint() instead of sscanf()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=d0057ca4c1fe73c05a9e077cc7691217370b3283;p=linux.git

arch/x86/mm/kmemcheck/kmemcheck.c: use kstrtoint() instead of sscanf()

Kmemcheck should use the preferred interface for parsing command line
arguments, kstrto*(), rather than sscanf() itself.  Use it
appropriately.
