This is a note to let you know that I've just added the patch titled tpm, tpm_tis: Extend locality handling to TPM2 in tpm_tis_gen_interrupt() to the 5.12-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: tpm-tpm_tis-extend-locality-handling-to-tpm2-in-tpm_tis_gen_interrupt.patch and it can be found in the queue-5.12 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. >From e630af7dfb450d1c00c30077314acf33032ff9e4 Mon Sep 17 00:00:00 2001 From: Jarkko Sakkinen <jarkko@xxxxxxxxxx> Date: Mon, 10 May 2021 15:28:30 +0300 Subject: tpm, tpm_tis: Extend locality handling to TPM2 in tpm_tis_gen_interrupt() From: Jarkko Sakkinen <jarkko@xxxxxxxxxx> commit e630af7dfb450d1c00c30077314acf33032ff9e4 upstream. The earlier fix (linked) only partially fixed the locality handling bug in tpm_tis_gen_interrupt(), i.e. only for TPM 1.x. Extend the locality handling to cover TPM2.
