+/* A driver for the D-Link DSB-R100 USB radio. The R100 plugs
+ into both the USB and an analog audio input, so this thing
+ only deals with initialisation and frequency setting, the
+ audio data has to be handled by a sound driver.
+
+ Major issue: I can't find out where the device reports the signal
+ strength, and indeed the windows software appearantly just looks
+ at the stereo indicator as well. So, scanning will only find
+ stereo stations. Sad, but I can't help it.
+
+ Also, the windows program sends oodles of messages over to the
+ device, and I couldn't figure out their meaning. My suspicion
+ is that they don't have any:-)

+ History:
+
+ Version 0.40:
+ Markus: Updates for 2.6.x kernels, code layout changes, name sanitizing
+
+ Version 0.30:
+ Markus: Updates for 2.5.x kernel and more ISO compliant source
+
+ Version 0.25:
+ PSL and Markus: Cleanup, radio now doesn't stop on device close
+
+ Version 0.24:
+ Markus: Hope I got these silly VIDEO_TUNER_LOW issues finally
+ right. Some minor cleanup, improved standalone compilation
+
+ Version 0.23:
+ Markus: Sign extension bug fixed by declaring transfer_buffer unsigned
+
+ Version 0.22:
+ Markus: Some (brown bag) cleanup in what VIDIOCSTUNER returns,
+ thanks to Mike Cox for pointing the problem out.
+
+ Version 0.21:
+ Markus: Minor cleanup, warnings if something goes wrong, lame attempt
+ to adhere to Documentation/CodingStyle
+
+ Version 0.2:
+ Brad Hards <bradh@dynamite.com.au>: Fixes to make it work as non-module
+ Markus: Copyright clarification
+
+ Version 0.01: Markus: initial release

-/* A driver for the D-Link DSB-R100 USB radio. The R100 plugs
- into both the USB and an analog audio input, so this thing
- only deals with initialisation and frequency setting, the
- audio data has to be handled by a sound driver.
-
- Major issue: I can't find out where the device reports the signal
- strength, and indeed the windows software appearantly just looks
- at the stereo indicator as well. So, scanning will only find
- stereo stations. Sad, but I can't help it.
-
- Also, the windows program sends oodles of messages over to the
- device, and I couldn't figure out their meaning. My suspicion
- is that they don't have any:-)

- History:
-
- Version 0.40:
- Markus: Updates for 2.6.x kernels, code layout changes, name sanitizing
-
- Version 0.30:
- Markus: Updates for 2.5.x kernel and more ISO compliant source
-
- Version 0.25:
- PSL and Markus: Cleanup, radio now doesn't stop on device close
-
- Version 0.24:
- Markus: Hope I got these silly VIDEO_TUNER_LOW issues finally
- right. Some minor cleanup, improved standalone compilation
-
- Version 0.23:
- Markus: Sign extension bug fixed by declaring transfer_buffer unsigned
-
- Version 0.22:
- Markus: Some (brown bag) cleanup in what VIDIOCSTUNER returns,
- thanks to Mike Cox for pointing the problem out.
-
- Version 0.21:
- Markus: Minor cleanup, warnings if something goes wrong, lame attempt
- to adhere to Documentation/CodingStyle
-
- Version 0.2:
- Brad Hards <bradh@dynamite.com.au>: Fixes to make it work as non-module
- Markus: Copyright clarification
-
- Version 0.01: Markus: initial release
