Subject: [PATCH 14/22] ACPICA: iASL: Add new warnings for method local_x and arg_x variables.

From: Bob Moore <robert.moore@...el.com>

ACPICA commit eb9f8cb9fd65f1149dd335d05944c31cbca41af3

1) Warn if a Local is set but never used
2) Warn if a arg_x is never used (for non-predefined method names)
3) Warn if a arg_x that is used as a local is never used

This patch only affects iASL which is not in the kernel source tree.
