This is incredibly puzzling. I could understand your board not booting
at all because of this patch, but an i2c device missing?

Can you see the i2c controller at all? I'll try to dig my PXA270 board
and see if I can reproduce your issue.

There are three i2c devices on my board:

static struct i2c_board_info spitz_i2c_devs[] = {
	{
		.type		= "wm8750",
		.addr		= 0x1b,
	}, {
		.type		= "max7310",
		.addr		= 0x18,
		.platform_data	= &akita_pca953x_pdata,
	},
};

These two are on bus 0.

static struct i2c_board_info spitz_pi2c_devs[] = {
	{
		.type		= "isl6271a",
		.addr		= 0x0c,
		.platform_data	= &isl6271a_info,
	},
};

This one is on bus 1.

With commit 424e5994e63326a42012f003f1174f3c363c7b62 applied
Only the max7310 is missing, the other two register and work fine.

Now, if i try to register _only_ the max7310 chip, it shows up but it doesn't
work. In that case i get this:

gpiochip_add: gpios 204..211 (max7310) failed to register
pca953x: probe of 0-0018 failed with error -16

Right. So what you need to do is find out why GPIOs 204 to 211 are
unavailable. Something must get clobbered one way or another.
