From 065bd8c28ba37d04c9a5b732173c1508954b1f58 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Tue, 13 Jan 2015 17:08:06 +0100 Subject: mlx5: avoid build warnings on 32-bit The mlx5 driver passes a string pointer in through a 'u64' variable, which on 32-bit machines causes a build warning: drivers/net/ethernet/mellanox/mlx5/core/debugfs.c: In function 'qp_read_field': drivers/net/ethernet/mellanox/mlx5/core/debugfs.c:303:11: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast] The code is in fact safe, so we can shut up the warning by adding extra type casts.
