Canned release function freeing memory allocated for the device allows drivers using such devices to be unloaded without waiting for the last reference to the device to be dropped\&. .PP This interface is primarily intended for use with legacy drivers which probe hardware directly\&. Because such drivers create sysfs device nodes themselves, rather than letting system infrastructure handle such device enumeration tasks, they don\*(Aqt fully conform to the Linux driver model\&. In particular, when such drivers are built as modules, they can\*(Aqt be \(lqhotplugged\(rq\&. .PP Returns struct platform_device pointer on success, or \fBERR_PTR\fR on error\&. .SH "COPYRIGHT" .br
