Subject: [34-longterm 187/209] USB: usb-storage: unusual_devs entry for the Samsung YP-CP3

From: Vitaly Kuznetsov <vitty@...linux.ru>

  =====================================================================
  | This is a commit scheduled for the next v2.6.34 longterm release. |
  | If you see a problem with using this for longterm, please comment.|
  =====================================================================

commit d73a9b3001f29271c2e9f2a806b05a431c5d9591 upstream.

Add an unusual_devs entry for the Samsung YP-CP3 MP4 player.

User was getting the following errors in dmesg:
 usb 2-6: reset high speed USB device using ehci_hcd and address 2
 usb 2-6: reset high speed USB device using ehci_hcd and address 2
 usb 2-6: reset high speed USB device using ehci_hcd and address 2
 usb 2-6: USB disconnect, address 2
 sd 3:0:0:0: [sdb] Assuming drive cache: write through
 sdb:<2>ldm_validate_partition_table(): Disk read failed.
 Dev sdb: unable to read RDB block 0
  unable to read partition table

[PG: change USB_ --> US_ to match 2.6.34.x naming conventions]
