From 7e019daf7ab9dca3bf782d6de866b36d44ede95e Mon Sep 17 00:00:00 2001 From: Tom Rini Date: Tue, 12 Apr 2016 15:11:22 -0400 Subject: [PATCH] drivers/tpm/tpm_tis_sandbox.c: Fix uninitialized variable use In rollback_space_kernel we were not initializing the reserved fields which should be for safety sake, and doing memset here means we don't need to set the version field specifically either.
