Greg,

I was just scanning this email and it looks like you possibly grabbed
the first of my patches with a typo because this last little bit I
corrected in a prior email to you. It got into the *mm* tree ok.
So I'm not sure where this took a wrong turn again.

Its the very last bit of the above patch on saa7146.h, where I'd at
first mistakenly managed to
change struct i2c_msg msgs[] to struct *i2c_msg msgs, when it should
have been changed to
struct i2c_msg *msgs as below. (Its just a cut and paste below, so it
might be easier if you just typed it into whatever version you've got now.

If its left uncorrected it'd give some sort of compiler error (to say
the least).

Thanks very much,

Mick
