Message-Id: <1371565167-27700-1-git-send-email-andriy.shevchenko@linux.intel.com> Date: Tue, 18 Jun 2013 17:19:27 +0300 From: Andy Shevchenko <andriy.shevchenko@...ux.intel.com> To: Mika Westerberg <mika.westerberg@...ux.intel.com>, Vinod Koul <vinod.koul@...el.com>, linux-kernel@...r.kernel.org Cc: Andy Shevchenko <andriy.shevchenko@...ux.intel.com> 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.
