So there is no reason to call peripheral_free_list again. Did I miss something else? >> out_error_req_irq: >> -out_error_no_irq: >> +out_error_pin_mux: >> peripheral_free_list((unsigned short *)pdev->dev.platform_data); >> -out_error_pin_mux: >> +out_error_no_irq: > > > Regards, > > Sonic > > > -- To unsubscribe from this list: send the line "unsubscribe linux-i2c" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
