Volunteers to test i2c-algo-8xx on v2.6?

[Joakim Tjernlund]

Hi

Had a look at my old driver and it needs a little care.

Basically this block has changed

> +		local_irq_save(flags);

> +		i2c->i2c_i2mod |= 1;	/* Enable */
> +		i2c->i2c_i2com |= 0x80;	/* Begin transmission */
> +
> +		/* Wait for IIC transfer */
> +		tmo = interruptible_sleep_on_timeout(&iic_wait,1*HZ);
> +		local_irq_restore(flags);
> +	} else { /* busy wait for small transfers, its faster */
> +		i2c->i2c_i2cmr = 0x00;	/* Disable I2C interupts */
> +		i2c->i2c_i2cer = 0xff;

I have done this for cpm_iic_read, cpm_iic_write and cpm_iic_try_address.
Also note the the addition of "| 0x01" to i2c->i2c_i2com.
