From 663be6e9f2773c98c9850b7e2797490b5f6caf8b Mon Sep 17 00:00:00 2001 From: Vladimir Serbinenko Date: Wed, 5 Nov 2014 21:29:45 +0100 Subject: acpigen: Add and use acpigen_write_device. The sequence of bytes to create a method is used several times in codebase. Put it into a function with logical arguments rather than duplicating magic bytes everywhere.
