From: Colin Ian King colin.king@canonical.com
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.
