Subject: acpi-dma: fix sparse warning
X-Git-Url: http://git.efficios.com/?a=commitdiff_plain;h=4aed508fc5a8314351bc3daa913a4713d52e6677;p=deliverable%2Flinux.git

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.
