[PATCH 1/1] USB: Nokia 502 is an unusual device

[Mikhail Zolotaryov]

The USB storage operation of Nokia Asha 502 Dual SIM smartphone running Asha
Platform 1.1.1 is unreliable in respect of data consistency (i.e. transfered
files are corrupted). A similar issue is described here:
http://discussions.nokia.com/t5/Asha-and-other-Nokia-Series-30/Nokia-301-USB-transfers-and-corrupted-files/td-p/1974170

The workaround is (MAX_SECTORS_64):
   rmmod usb_storage && modprobe usb_storage quirks=0421:06aa:m

The patch adds the tested device to the unusual list permanently.
