From 3e43cfa3466178ec7f4309031647e93565bc70bf Mon Sep 17 00:00:00 2001 From: Kexy Biscuit kexybiscuit@aosc.io Date: Mon, 2 Sep 2024 08:26:38 +0800 Subject: [PATCH] tpm: export tpm2_sessions_init() to fix ibmvtpm building
Commit 08d08e2e9f0a ("tpm: ibmvtpm: Call tpm2_sessions_init() to initialize session support") adds call to tpm2_sessions_init() in ibmvtpm, which could be built as a module. However, tpm2_sessions_init() wasn't exported, causing libmvtpm to fail to build as a module:
ERROR: modpost: "tpm2_sessions_init" [drivers/char/tpm/tpm_ibmvtpm.ko] undefined!
Export tpm2_sessions_init() to resolve the issue.
