Koskinen, Aaro (Nokia - FI/Espoo) Feb. 18, 2009, 9:22 a.m. UTC
Fixes a linker error when OMAP I2C bus driver is compiled as a module:

   ERROR: "i2c_register_board_info" [arch/arm/plat-omap/i2c.ko] undefined!

The I2C utility functions used for board initialization should be always
built-in.

Heh, OK pushed there too :) I think we should close that branch soon
as 2.6.29 is fast approaching..
