[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Changes in v9:
- add a function tpm_devs_remove() as counterpart to tpm_devs_add()
  as suggested by Jason

Changes in v8:
- adjust names of jump labels for 
  as requested by Jarkko

Changes in v7:
- adjust naming of jump labels to fit better the used label naming scheme

Changes in v6:
- rename function tpm2_add_device() to tpm_devs_add() as requested by Jarko
- add function descriptions
- fix source code formatting

Changes in v5:
- move function tpm_add_tpm2_char_device() to tpm2-space.c and rename
it to tpm2_add_device() as requested by Jarko
- put "cc" tag before all other tags 
- ensure that the error path in tpm2_add_device() always calls 
the release() function of chip->devs as requested by Jason
- reformat a code line as suggested by David Laight

Changes in v4:
- drop patch 2 (tpm: in tpm2_del_space check if ops pointer is still
valid) since James Bottomley offered a cleaner solution for this
- reimplement patch 1 to setup the /dev/tpmrm device only in case of TPM2
and avoid the installation of another action handler. This is based on a
suggestion and basic implementation done by Jason Gunthorpe.
- added tag to CC stable

Changes in v3:
- drop the patch that introduces the new function tpm_chip_free()
- rework the commit messages for the patches (style, typos, etc.)
- add fixes tag to patch 2
- add James Bottomley to cc list
- add stable mailing list to cc list

Changes in v2:
- drop the patch that erroneously cleaned up after failed installation of
  an action handler in tpmm_chip_alloc() (pointed out by Jarkko Sakkinen)
- make the commit message for patch 1 more detailed
- add fixes tags and kernel logs
