Subject: mlx5: avoid build warnings on 32-bit
From: Arnd Bergmann <arnd@arndb.de>
commit 065bd8c28ba37d04c9a5b732173c1508954b1f58 upstream.
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.
