tpm: fix (ACPI S3) suspend regression
This patch fixes an (ACPI S3) suspend regression introduced in commit 68d6e6713fcb ("tpm: Introduce function to poll for result of self test") and occurring with an Infineon TPM and tpm_tis and tpm_infineon drivers active. The suspend problem occurred if the TPM was disabled and/or deactivated and therefore the TPM_PCRRead checking the result of the (asynchronous) self test returned an error code which then caused the tpm_tis driver to become inactive and this then seemed to have negatively influenced the suspend support by the tpm_infineon driver... Besides that the tpm_tis drive may stay active even if the TPM is disabled and/or deactivated. Signed-off-by: Stefan Berger <stefanb@linux.vnet.ibm.com> Tested-by: Rafael J.
