hwmon: (acpi_power_meter) fix lockdep spew due to non-static lock class
Similar to a30dcb4f which fixed asus_atk0110.ko, I recently received a bug report from someone hitting the same issue in acpi_power_meter. [ 13.963168] power_meter ACPI000D:00: Found ACPI power meter. [ 13.963900] BUG: key ffff8802161f3920 not in .data! [ 13.963904] ------------[ cut here ]------------ [ 13.963915] WARNING: at kernel/lockdep.c:2986 lockdep_init_map+0x52f/0x560() So let's fix that up for them by statically declaring the lockdep_class_key.
