The ad7418 driver is only used on embedded platforms where i2c devices can easily be declared in platform code. Thus a new-style i2c driver makes perfect sense. This lets us get rid of quirky detection code (these chips have no identification registers) and shrinks the binary driver size by 38%.

The new-style ds2482 driver implements the optional detect() callback to cover the use cases of the legacy driver. I'm curious if anyone really needs this though, so it might be removed in the feature. Signed-off-by: NJean Delvare <khali@linux-fr.org>

The new-style pca9539 driver implements the optional detect() callback to cover the use cases of the legacy driver. Warning: users will now have to use the force module parameter to get the driver to attach to their device. That's not a bad thing as these devices can't be detected anyway. Note that this doesn't change the fact that this driver is deprecated in favor of gpio/pca953x. Signed-off-by: NJean Delvare <khali@linux-fr.org>

Clear i2c_adapter.dev on adapter removal. This makes it possible to re-add the adapter at a later point, which some drivers (i2c-amd756-s4882, i2c-nforce2-s4985) actually do. This fixes a bug reported by John Stultz here: http://lkml.org/lkml/2008/7/15/720 and by Ingo Molar there: http://lkml.org/lkml/2008/7/16/78Signed-off-by: NJean Delvare <khali@linux-fr.org> Cc: John Stultz <johnstul@us.ibm.com> Cc: Ingo Molnar <mingo@elte.hu>
