[PATCH] tpm_tis: Fix interrupt probing

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Stefan Berger <stefanb@xxxxxxxxxxxxx>

The interrupt probing of the TPM TIS was broken since we are trying to
run it without an active locality and without the TPM_CHIP_FLAG_IRQ set.
