X-Git-Url: http://git.ipfire.org/gitweb/?a=commitdiff_plain;h=64762d48ec84d36fc2618920a731368387253efc;p=thirdparty%2Fkernel%2Flinux.git

thermal: sysfs: Replace sscanf() with kstrtoul()

Replace sscanf() with kstrtoul() in cur_state_store(), as kstrto<type>
is preferred over single-variable sscanf().
