Revert commit e918e570415c ("tpm_tis: Remove the HID IFX0102")
Removing IFX0102 from tpm_tis was not a right move because both tpm_tis and tpm_infineon use the same device ID. Revert the commit and add a remark about a bug caused by commit 93e1b7d42e1e ("[PATCH] tpm: add HID module parameter"). Fixes: e918e570415c ("tpm_tis: Remove the HID IFX0102") Reported-by: Peter Huewe <peterhuewe@gmx.de> Reviewed-by: Jerry Snitselaar <jsnitsel@redhat.com> Signed-off-by: Jarkko Sakkinen <jarkko.sakkinen@linux.intel.com>
