From 0d709d91b85b71568b41b323d2a2c761f18e5213 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Tue, 14 May 2013 21:20:02 +0000 Subject: [PATCH] ipg: fix an unsigned widening cast of '~' truncation issue The bug here is this code from ipg_nic_hard_start_xmit(): txfd->tfc &= cpu_to_le64(~IPG_TFC_TFDDONE); IPG_TFC_TFDDONE is 0x0000000080000000 so it's an unsigned int. The negated value is 0x7fffffff but 0xffffffff7fffffff was intended. The other values in this file don't need to be changed but I did it for consistency.
