* - code cleaned of unnecessary rds_commands
* - USB Vendor/Product ID for ADS/Tech FM Radio Receiver verified
* (thanks to Guillaume RAMOUSSE)
* 2008-01-27 Tobias Lorenz <tobias.lorenz@gmx.net>
* Version 1.0.5
* - number of seek_retries changed to tune_timeout
* - fixed problem with incomplete tune operations by own buffers
* - optimization of variables and printf types
* - improved error logging
* 2008-01-31 Tobias Lorenz <tobias.lorenz@gmx.net>
* Oliver Neukum <oliver@neukum.org>
* Version 1.0.6
* - fixed coverity checker warnings in *_usb_driver_disconnect
* - probe()/open() race by correct ordering in probe()
* - DMA coherency rules by separate allocation of all buffers
* - use of endianness macros
* - abuse of spinlock, replaced by mutex
* - racy handling of timer in disconnect,
* replaced by delayed_work
* - racy interruptible_sleep_on(),
* replaced with wait_event_interruptible()
* - handle signals in read()
* 2008-02-08 Tobias Lorenz <tobias.lorenz@gmx.net>
* Oliver Neukum <oliver@neukum.org>
* Version 1.0.7
* - usb autosuspend support
*
* ToDo:
* - add seeking support
