From 57b2eaf7ddeae307fac202d82a6fabf5976e575b Mon Sep 17 00:00:00 2001 From: FUJITA Tomonori Date: Wed, 7 Jul 2010 23:52:37 +0000 Subject: [PATCH] cxgb4vf: remove obsolete DECLARE_PCI_UNMAP_ADDR usage We could use DEFINE_DMA_UNMAP_ADDR instead but using CONFIG_NEED_DMA_MAP_STATE is a simpler way to see if a platform does real DMA unmapping.
