From 4fa5518c65df7a2c4b6c58061ac53d0b01228042 Mon Sep 17 00:00:00 2001 From: Eric Miao Date: Sat, 5 Jun 2010 15:16:17 +0800 Subject: [ARM] pxa: remove now unnecessary dma_needs_bounce() With a correct dev->dma_mask before calling dmabounce_register_dev(), dma_needs_bounce() is not necessary. The sa1111, though, is a bit complicated. Until it's fully understood and fixed, dma_needs_bounce() for sa1111 is kept if CONFIG_SA1111 is enabled with no side effect (with the condition of machine_is_*) Thanks for Mike Rapoport to fix one error in the original version of the patch and get this tested.
