From 95ebcea69c888fc644e2a64586c74e2299ca47ca Mon Sep 17 00:00:00 2001 From: Joachim Eastwood Date: Mon, 22 Oct 2012 08:45:31 +0000 Subject: [PATCH] net/macb: fix truncate warnings When building macb on x86_64 the following warnings show up: drivers/net/ethernet/cadence/macb.c: In function macb_interrupt: drivers/net/ethernet/cadence/macb.c:556:4: warning: large integer implicitly truncated to unsigned type [-Woverflow] drivers/net/ethernet/cadence/macb.c: In function macb_reset_hw: drivers/net/ethernet/cadence/macb.c:792:2: warning: large integer implicitly truncated to unsigned type [-Woverflow] drivers/net/ethernet/cadence/macb.c:793:2: warning: large integer implicitly truncated to unsigned type [-Woverflow] drivers/net/ethernet/cadence/macb.c:796:2: warning: large integer implicitly truncated to unsigned type [-Woverflow] Use -1 insted of ~0UL, as done in other places in the driver, to silence these warnings.
