Subject: hwmon: (peci/cputemp) Fix off-by-one in coretemp_label allocation
From: Zev Weiss <zev@xxxxxxxxxxxxxxxxx>
commit f00093608fa790580da309bb9feb5108fbe7c331 upstream.
The find_last_bit() call produces the index of the highest-numbered
core in core_mask; because cores are numbered from zero, the number of
elements we need to allocate is one more than that.
