Use the error code returned by the vnt_control_out function as the returned value of the vnt_rf_write_embedded function instead of a boolean value. Then, fix all vnt_rf_write_embedded calls removing the "and" operations and replace with a direct assignment to the ret variable and add a check condition after every call. Also replace the boolean values true or false in the vnt_rf_set_txpower function to 0 or error code EINVAL to follow the coding style guide. The vnt_rf_set_txpower function is called only in the vnt_rf_setpower function that already returns error codes. The calls to this function (vnt_rf_set_txpower) not use the returned values, so they not need to be fixed.
