tpm_tis: Remove the HID IFX0102
Acer C720 running Linux v5.3 reports this in klog: tpm_tis: 1.2 TPM (device-id 0xB, rev-id 16) tpm tpm0: tpm_try_transmit: send(): error -5 tpm tpm0: A TPM error (-5) occurred attempting to determine the timeouts tpm_tis tpm_tis: Could not get TPM timeouts and durations tpm_tis 00:08: 1.2 TPM (device-id 0xB, rev-id 16) tpm tpm0: tpm_try_transmit: send(): error -5 tpm tpm0: A TPM error (-5) occurred attempting to determine the timeouts tpm_tis 00:08: Could not get TPM timeouts and durations ima: No TPM chip found, activating TPM-bypass! tpm_inf_pnp 00:08: Found TPM with ID IFX0102 % git --no-pager grep IFX0102 drivers/char/tpm drivers/char/tpm/tpm_infineon.c: {"IFX0102", 0}, drivers/char/tpm/tpm_tis.c: {"IFX0102", 0}, /* Infineon */ Obviously IFX0102 was added to the HID table for the TCG TIS driver by mistake.
