In meson_pwm_probe the for loop attempts to get the name of a clock but
the following if..else statements only perform useful work if -ENODATA
is returned from clk_get_by_name. If clk_get_by_name simply succeeds
then this results in a premature exit from the for loop and the
following code can never be reached. Make the else clause only apply for
an error return from clk_get_by_name.
This issue was found by Smatch.
