When acpi_drv->ops.remove() failed, I thought we would need to roll-back the procedure done by the acpi_device_remove_notify_handler() call, which I indicated as "THIS CALL" above. So, in this error path, don't we need something like below? if (acpi_drv->ops.notify) acpi_device_install_notify_handler(acpi_dev) Thanks, -Toshi -- To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
