net: ethernet: lpc_eth: Handle error for clk_enable
As the potential failure of the clk_enable(), it should be better to check it and return error if fails. Fixes: b7370112f519 ("lpc32xx: Added ethernet driver") Signed-off-by: Jiasheng Jiang <jiasheng@iscas.ac.cn> Signed-off-by: David S. Miller <davem@davemloft.net>
