[PATCH] i2c.h: Fix another gcc 4.0 compile failure

[Mickey Stein]

From: Mickey Stein
 Versions:   linux-2.6.11-rc4-bk7, gcc4 (GCC) 4.0.0 20050217 (latest fc 
rawhide from 19Feb DL)

 gcc4 cvs seems to dislike "include/linux/i2c.h file":

 Error msg:   include/linux/i2c.h:{55,194} error: array type has 
incomplete element type

 A. Daplas has recently done a workaround for this on another header 
file. A thread discussing this
 can be found by following the link below:

 http://gcc.gnu.org/ml/gcc/2005-02/msg00053.html

 The patch changes the array declaration from "struct x y[]" format to 
"struct x *y".
 I realize its only a workaround, but the gcc guys seem to be aware of 
this.
 ** Note: I'm a noob at this, so feel free to make chopped liver out of 
this if its incorrect.
 patch below is also attached since I'm not sure formatting survives 
the cut&paste.
