V4L/DVB (3100): fix compile error, remove dead code and volume scaling
- Fix compile error (missing '}') in em28xx-video.c. Remove dead code and volume scaling from msp3400.c. Volume scaling does not belong there, it should be done in the driver for the card that uses the msp3400 if needed, not in the msp3400.c source. The volume scaling code gave problems with the ivtv driver which does not need to do any scaling.
