The new-style pcf8574 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/pcf857x. Signed-off-by: Jean 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: Jean Delvare <khali@linux-fr.org> Cc: John Stultz <johnstul@us.ibm.com> Cc: Ingo Molnar <mingo@elte.hu>
