clk_enable() may fail, so you should check its return value.The check seems a little superfluous because the failure condition for clk_enable is (clk == NULL || IS_ERR(clk)) Once this function is called which means the initialization of the driver is successful.
Not superfluos. You can't assume that clk_enable() will always be successful. Better check its return value.
