From 3a8954e8f22cf31791d8c524c2839433e39f9368 Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Fri, 26 Feb 2010 17:58:07 -0700 Subject: [PATCH] staging: dt3155: revert u_long to u64 usage Commit 9c1390a923ddb6fba1cf9d7440743369140c6d8a replaced all u_int's with u32 and u_long's with u64. Unfortunately, a u_long is still only 32-bits so they should have been replaced with u32 also. This can be verified by the register definitions in dt3155_io.h. It specifically states that the memory mapped registers are 32-bit. Fix this by changing all the u64 to u32.
