Jacob Pan aa3ee06a2a powercap/intel_rapl: fix and tidy up error handling ... commit cb43f81b84 upstream. Commit e1399ba20e ("powercap / RAPL: handle missing MSRs") added contraint_to_pl() function to return index into an array. But it can potentially return -EINVAL if powercap layer sends an out of range constraint ID. This patch adds sanity check. Unnecessary RAPL domain pointer check is removed since it must be initialized before calling rapl_unit_xlate().
