Currently, the check that ret_val is not -ENOENT is always true and
the quirk bit BYT_RY5651_MCLK_EN is never being cleared because ret_val
is always zero at this point from a previous assignment earlier on.
I believe that ret_val should actually be assigned to the return from
devm_clk_get() as this can return -ENOENT (from a deeper call to
clk_get_sys) and that was the original intention to check this.

nice catch, the fix is consistent with what is done for rt5640.
