Today's linux-next build (powerpc ppc64_defconfig) fails like this:

arch/powerpc/platforms/pasemi/misc.c: In function 'find_i2c_driver':
arch/powerpc/platforms/pasemi/misc.c:43: error: 'struct i2c_board_info' has no member named 'driver_name'
arch/powerpc/platforms/pasemi/misc.c:44: error: 'struct i2c_board_info' has no member named 'driver_name'
arch/powerpc/platforms/pasemi/misc.c:44: error: 'struct i2c_board_info' has no member named 'driver_name'

So I reverted commit f625810ef235a8b238427df3129792f89187c085 ("i2c: Kill
the old driver matching scheme").  Obviously not the correct fix, but it
makes the build work.

Thanks for the notification and sorry for the trouble. I thought that I
knew about all users of struct i2c_board_info and that they were all
converted by now but obviously not. I didn't know that fsl_soc.c had
been partly forked for the pasemi platform.

Here's a fix, it's the same that was applied to fsl_soc.c:

Olof, please test it if you can. I will push this patch to Linux
quickly.

Stephen, I'm updating my i2c tree now and you'll get this patch under
the name i2c-02-switch-pasemi-to-module-aliases.patch. Note that this
will cause one more conflict with Greg KH driver tree, which you can
solve the same way you solved the other ones.

Thanks,
