From 4aed508fc5a8314351bc3daa913a4713d52e6677 Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Mon, 15 Jul 2013 15:04:36 +0300 Subject: [PATCH] acpi-dma: fix sparse warning This patch fixes sparse warning: drivers/dma/acpi-dma.c:76:21: sparse: cast to restricted __le32 Since everything in all ACPI tables is little-endian, by definition, the used types in practice are uXX. Thus, we have to enforce __leXX if we want to convert them to CPU order.
