tty: serial: 8250_mtk: Use devm_clk_get
Browse files Browse the repository at this point in the history
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.
