USB: rio500: Remove Rio 500 kernel driver

commit 015664d15270a112c2371d812f03f7c579b35a73 upstream.

The Rio500 kernel driver has not been used by Rio500 owners since 2001
not long after the rio500 project added support for a user-space USB stack
through the very first versions of usbdevfs and then libusb.

Support for the kernel driver was removed from the upstream utilities
in 2008:

-OVERVIEW
-
-This README will address issues regarding how to configure the kernel
-to access a RIO 500 mp3 player.  
-Before I explain how to use this to access the Rio500 please be warned:
-
-W A R N I N G:
---------------
-
-Please note that this software is still under development.  The authors
-are in no way responsible for any damage that may occur, no matter how
-inconsequential.
-
-It seems that the Rio has a problem when sending .mp3 with low batteries.
-I suggest when the batteries are low and you want to transfer stuff that you
-replace it with a fresh one. In my case, what happened is I lost two 16kb
-blocks (they are no longer usable to store information to it). But I don't
-know if that's normal or not; it could simply be a problem with the flash 
-memory.
-
-In an extreme case, I left my Rio playing overnight and the batteries wore 
-down to nothing and appear to have corrupted the flash memory. My RIO 
-needed to be replaced as a result.  Diamond tech support is aware of the 
-problem.  Do NOT allow your batteries to wear down to nothing before 
-changing them.  It appears RIO 500 firmware does not handle low battery 
-power well at all. 
-
-On systems with OHCI controllers, the kernel OHCI code appears to have 
-power on problems with some chipsets.  If you are having problems 
-connecting to your RIO 500, try turning it on first and then plugging it 
-into the USB cable.

-   The main page for the project is hosted at sourceforge.net in the following
-   URL: <http://rio500.sourceforge.net>. You can also go to the project's
-   sourceforge home page at: <http://sourceforge.net/projects/rio500/>.
-   There is also a mailing list: rio500-users@lists.sourceforge.net

-Authors:
--------
-
-Most of the code was written by Cesar Miquel <miquel@df.uba.ar>. Keith 
-Clayton <kclayton@jps.net> is incharge of the PPC port and making sure
-things work there. Bruce Tenison <btenison@dibbs.net> is adding support
-for .fon files and also does testing. The program will mostly sure be
-re-written and Pete Ikusz along with the rest will re-design it. I would
-also like to thank Tri Nguyen <tmn_3022000@hotmail.com> who provided use 
-with some important information regarding the communication with the Rio.

-ADDITIONAL INFORMATION and Userspace tools
-
-http://rio500.sourceforge.net/
-
-
-REQUIREMENTS
-
-A host with a USB port.  Ideally, either a UHCI (Intel) or OHCI
-(Compaq and others) hardware port should work.
-
-A Linux development kernel (2.3.x) with USB support enabled or a
-backported version to linux-2.2.x.  See http://www.linux-usb.org for
-more information on accomplishing this.
-
-A Linux kernel with RIO 500 support enabled.
-
-'lspci' which is only needed to determine the type of USB hardware
-available in your machine.
-
-CONFIGURATION
-
-Using `lspci -v`, determine the type of USB hardware available.
-
-  If you see something like:
-
-    USB Controller: ......
-    Flags: .....
-    I/O ports at ....
-
-  Then you have a UHCI based controller.
-
-  If you see something like:
-
-     USB Controller: .....
-     Flags: ....
-     Memory at .....
-
-  Then you have a OHCI based controller.
-
-Using `make menuconfig` or your preferred method for configuring the
-kernel, select 'Support for USB', 'OHCI/UHCI' depending on your
-hardware (determined from the steps above), 'USB Diamond Rio500 support', and
-'Preliminary USB device filesystem'.  Compile and install the modules
-(you may need to execute `depmod -a` to update the module
-dependencies).
-
-Add a device for the USB rio500:
-  `mknod /dev/usb/rio500 c 180 64`
-
-Set appropriate permissions for /dev/usb/rio500 (don't forget about
-group and world permissions).  Both read and write permissions are
-required for proper operation.
-
-Load the appropriate modules (if compiled as modules):
-
-  OHCI:
-    modprobe usbcore
-    modprobe usb-ohci
-    modprobe rio500
-
-  UHCI:
-    modprobe usbcore
-    modprobe usb-uhci  (or uhci)
-    modprobe rio500
-
-That's it.  The Rio500 Utils at: http://rio500.sourceforge.net should
-be able to access the rio500.
