cpufreq: powernow-k8: Fix possible memory leak in powernowk8_cpu_init()

mirror of https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git synced 2026-08-09 06:14:34 +02:00

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().
