Subject[26/30] i2c: Do not use device name after device_unregister
2.6.32-stable review patch.  If anyone has any objections, please let us know.

From: Thadeu Lima de Souza Cascardo <>

commit c556752109794a5ff199b80a1673336b4df8433a upstream.

dev_dbg outputs dev_name, which is released with device_unregister. This bug
resulted in output like this:

i2c Xy2�0: adapter [SMBus I801 adapter at 1880] unregistered

The right output would be:
i2c i2c-0: adapter [SMBus I801 adapter at 1880] unregistered
