Commit 4d17aeb1c5b2375769446d13012a98e6d265ec13 ("OMAP: I2C: split
device registration and convert OMAP2+ to omap_device") makes
omap2_i2c_add_bus() return a pointer to an omap_device instead on
success instead of 0.
This breaks the omap_register_i2c_bus() ABI and results in the igep0020
board code detecting an I2C bus registration error when there is none.
Fix the problem by using PTR_RET() instead of PTR_ERR() in
omap2_i2c_add_bus().
