LDD3 Errata

When I read Chapter 3 - Char Drivers of the LDD3 from internet, I found request_chrdev_region seems to be a typo of register_chrdev_region, and then found the errata of this book. Please refer to this page for detail. http://oreilly.com/catalog/linuxdrive3/errata/ You can find the on-line book of Linux Device Drivers, Third Edition in O'Reilly Open Books Project :)
