BITS_RX_EN is an 'unsigned long' constant, so the ones complement of that
has bits set that do not fit into a 32-bit variable on 64-bit architectures,
which causes a harmless gcc warning:
drivers/net/ethernet/hisilicon/hix5hd2_gmac.c: In function
'hix5hd2_port_disable':
drivers/net/ethernet/hisilicon/hix5hd2_gmac.c:374:2: warning: large integer
implicitly truncated to unsigned type [-Woverflow]
writel_relaxed(~(BITS_RX_EN | BITS_TX_EN), priv->base + PORT_EN);
This adds a cast to (u32) to tell gcc that the code is indeed fine.
