driver/char/tpm: fix regression causesd by ppi
This patch try to fix the S3 regression https://lkml.org/lkml/2012/10/5/433, which includes below line: [ 1554.684638] sysfs: cannot create duplicate filename '/devices/pnp0/00:0c/ppi' The root cause is that ppi sysfs teardown code is MIA, so while S3 resume, the ppi kobject will be created again upon existing one. To make the tear down code simple, change the ppi subfolder creation from using kobject_create_and_add to just using a named ppi attribute_group. Then ppi sysfs teardown could be done with a simple sysfs_remove_group call. Adjusted the name & return type for ppi sysfs init function.
