Subject: [26/30] i2c: Do not use device name after device_unregister
Date: Wed, 20 Jan 2010 20:15:47 -0800 [thread overview]

2.6.32-stable review patch. If anyone has any objections, please let us know.
------------------
From: Thadeu Lima de Souza Cascardo <cascardo@holoscopio.com>
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
