tpm: fix call order in tpm-chip.c
- tpm_dev_add_device(): cdev_add() must be done before uevent is propagated in order to avoid races. - tpm_chip_register(): tpm_dev_add_device() must be done as the last step before exposing device to the user space in order to avoid races. In addition clarified description in tpm_chip_register(). Fixes: 313d21ee ("tpm: device class for tpm") Fixes: afb5abc2 ("tpm: two-phase chip management functions") Signed-off-by: Jarkko Sakkinen <jarkko.sakkinen@linux.intel.com> Reviewed-by: Peter Huewe <peterhuewe@gmx.de> Signed-off-by: Peter Huewe <peterhuewe@gmx.de>
