[PATCH 40/79] V4L/DVB (3275) Split msp3400.c into msp3400-driver.cand msp3400-kthreads.c

[mchehab]

From: Hans Verkuil <hverkuil@xxxxxxxxx>

- Split msp3400.c into msp3400-driver.c and msp3400-kthreads.c.
- Removed experimental DFPREG ioctls. If this is really needed one
day then it should be implemented using VIDIOC_G/S_REGISTER.
- Added missing BALANCE control info for VIDIOC_QUERYCTRL.
- Still more cleanup, clarified some kernel messages.

+ * Programming the mspx4xx sound processor family
+ *
+ * (c) 1997-2001 Gerd Knorr <kraxel@xxxxxxxxxxx>
+ *
+ * what works and what doesn't:
+ *
+ *  AM-Mono
+ *      Support for Hauppauge cards added (decoding handled by tuner) added by
+ *      Frederic Crozat <fcrozat@xxxxxxxxxxxxxx>
+ *
+ *  FM-Mono
+ *      should work. The stereo modes are backward compatible to FM-mono,
+ *      therefore FM-Mono should be allways available.
+ *
+ *  FM-Stereo (B/G, used in germany)
+ *      should work, with autodetect
+ *
+ *  FM-Stereo (satellite)
+ *      should work, no autodetect (i.e. default is mono, but you can
+ *      switch to stereo -- untested)
+ *
+ *  NICAM (B/G, L , used in UK, Scandinavia, Spain and France)
+ *      should work, with autodetect. Support for NICAM was added by
+ *      Pekka Pietikainen <pp@xxxxxxxxx>
+ *
+ * TODO:
+ *   - better SAT support

- * programming the msp34* sound processor family
- *
- * (c) 1997-2001 Gerd Knorr <kraxel@xxxxxxxxxxx>
- *
- * what works and what doesn't:
- *
- *  AM-Mono
- *      Support for Hauppauge cards added (decoding handled by tuner) added by
- *      Frederic Crozat <fcrozat@xxxxxxxxxxxxxx>
- *
- *  FM-Mono
- *      should work. The stereo modes are backward compatible to FM-mono,
- *      therefore FM-Mono should be allways available.
- *
- *  FM-Stereo (B/G, used in germany)
- *      should work, with autodetect
- *
- *  FM-Stereo (satellite)
- *      should work, no autodetect (i.e. default is mono, but you can
- *      switch to stereo -- untested)
- *
- *  NICAM (B/G, L , used in UK, Scandinavia, Spain and France)
- *      should work, with autodetect. Support for NICAM was added by
- *      Pekka Pietikainen <pp@xxxxxxxxx>
- *
- *
- * TODO:
- *   - better SAT support
- *
