From 9834f81314b2a5b1bb3cd0d8f46e61528b60d580 Mon Sep 17 00:00:00 2001 From: Russell King Date: Fri, 8 Nov 2013 18:10:42 +0000 Subject: ARM: omap: move dma channel allocation into plat-omap code This really needs to be there, because otherwise the plat-omap code can kfree() this data structure, and then re-use the pointer later.
