[PATCH] I2C: Fix some gcc 4.0 compile failures and warnings
gcc 4.0.x cvs seems to dislike "include/linux/i2c.h file" and others due
to a current gcc 4.0.x change having to do with array declarations.
Example 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(struct i2c_msg) declaration used by
*i2c_transfer and *master_xfer from "struct i2c_msg msg[]" format to
"struct i2c_msg *msg".
After some grepping, I came up with about a dozen files that used the
format disliked by gcc4 that're addressed by the attached patch.
Tested on gcc 3.x & gcc 4.x by configuring kernel with all i2c switches
enabled as module, and saw no errors or warnings in i2c.
