From 01d0a9b474661831cd1ee5d88d5ee3fb80b55a7a Mon Sep 17 00:00:00 2001 From: Joe Perches Date: Tue, 26 Feb 2013 16:33:11 -0800 Subject: [PATCH] staging: slicoss: Remove dma_addr_t cast compilation warnings Eliminate some warnings by casting to unsigned long before casting a dma_addr_t value to a pointer. btw: Does slicoss always work on x86-32? Is a pshmem guaranteed to be accessible by a 32 bit address?
