tty: serial: 8250_mtk: Use devm_clk_get
When a struct device * is present clk_get should be used rather than of_clk_get. Use the devm variant of this function to be able to drop the clk_put in the error and remove pathes. While at it fix a wrong error message. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
