From 9f7e45d83ef09a481cbc4172849bd1fcf88a39ed Mon Sep 17 00:00:00 2001 From: Santosh Shilimkar Date: Mon, 29 Jul 2013 14:17:54 +0100 Subject: ARM: 7794/1: block: Rename parameter dma_mask to max_addr for blk_queue_bounce_limit() The blk_queue_bounce_limit() API parameter 'dma_mask' is actually the maximum address the device can handle rather than a dma_mask. Rename it accordingly to avoid it being interpreted as dma_mask. No functional change. The idea is to fix the bad assumptions about dma_mask wherever it could be miss-interpreted.
