"__devinit[data]" has not yet been used for all initialization functions
and data. To avoid truncating lines, the struct "mpc_i2c_match_data" has
been renamed to "mpc_i2c_data", which is even the better name.

Between patch 1 & 2 is not bisectable.  Functions still called
*_setclock in this patch, but referenced as *_setup in the structure.
Please respin.

Argh, sorry for the mess. I will fix it tomorrow.

... what was wrong with the old format of declaring the .data
structures inline with the match table?

It does not allow to use __devinitdata because the space reserved by the
compiler does belong to another section. In other words it was necessary
to get ride of section mismatches.
