The patch titled
tpm: fix ordering bug in error path
has been added to the -mm tree. Its filename is

See http://www.zip.com.au/~akpm/linux/patches/stuff/added-to-mm.txt to find
out what to do about this
From: Kylene Jo Hall <kjhall@xxxxxxxxxx>
The clear_bit of chip->dev_num ended up after the kfree of chip in the
error path of the tpm_register_hardware function. This patch fixes things
to avoid a potential segmentation fault.
This bug was found by Coverity.
