Jean-François Moine 780e312175 [media] gspca: Fix coding style issues 
The errors were found by checkpatch.pl. Most fixes are:
- remove spaces followed by TAB(s),
- split lines greater than 80 characters,
- move most '{'s from start of line to end of previous line.
  (Some '{'s at start of line remain when the '}'s are on the same line)
