Subject: [PATCH 2.6] New chip driver: pcf8574

Hi Greg,

Please find below a patch against kernel 2.6.5-rc1 to add the pcf8574 driver (an I/O expander for the I2C bus). I have ported it from the 2.4 version, and it includes some fixes and simplifications.

It has been reviewed by Jean Delvare on IRC.

Thanks,
Aurelien
