From ee8209fd026b074bb8eb75bece516a338a281b1b Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Wed, 8 May 2013 11:55:48 +0300 Subject: dma: acpi-dma: parse CSRT to extract additional resources Since we have CSRT only to get additional DMA controller resources, let's get rid of drivers/acpi/csrt.c and move its logic inside ACPI DMA helpers code.
