From 29cb79795e324a8b65e7891d76f8f6ca911ba440 Mon Sep 17 00:00:00 2001 From: Tianjia Zhang Date: Tue, 14 Apr 2020 19:42:26 +0800 Subject: [PATCH] tpm: fix wrong return value in tpm_pcr_extend For the algorithm that does not match the bank, a positive value EINVAL is returned here. I think this is a typo error. It is necessary to return an error value.
