---------------------------
What: i2c_adapter.dev
i2c_adapter.list
When: July 2007
Why: Superfluous, given i2c_adapter.class_dev:
* The "dev" was a stand-in for the physical device node that legacy
drivers would not have; but now it's almost always present. Any
remaining legacy drivers must upgrade (they now trigger warnings).
* The "list" duplicates class device children.
The delay in removing this is so upgraded lm_sensors and libsensors
can get deployed. (Removal causes minor changes in the sysfs layout,
notably the location of the adapter type name and parenting the i2c
client hardware directly from their controller.)
Who: Jean Delvare <khali@linux-fr.org>,

---------------------------
What: IPv4 only connection tracking/NAT/helpers
When: 2.6.22
Why: The new layer 3 independant connection tracking replaces the old

This driver can also be built as a module. If so, the module
will be called i2c-pnx.
config I2C_PNX_EARLY
bool "Early initialization for I2C on PNXxxxx"
depends on I2C_PNX=y
help
Under certain circumstances one may need to make sure I2C on PNXxxxx
is initialized earlier than some other driver that depends on it
(for instance, that might be USB in case of PNX4008). With this
option turned on you can guarantee that.
