If anyone has any objections, please let me know. ------------------ From: Abdun Nihaal commit d5f8e5f6040d052d44fcbf4f31dd35145c0c8d7d upstream. The memory allocated for data->powernow_table inside powernow_k8_cpu_init_acpi() or find_psb_table() is not freed in one of the error paths in powernowk8_cpu_init(). Fix that by adding a kfree().
