This patch fixes a reference count issue in the TPM core code. It is based on a suggestion and basic implementation made by Jason Gunthorpe. 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 - add proper tag for 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 Lino Sanfilippo (1): tpm: fix reference counting for struct tpm_chip drivers/char/tpm/tpm-chip.c | 80 ++++++++++++++++++++++++++++----------------- 1 file changed, 50 insertions(+), 30 deletions(-) -- 2.7.4
