From fe265a1b9ce7ad5b3dbd19f5857a902494bbe24e Mon Sep 17 00:00:00 2001 From: Aaron Durbin Date: Fri, 15 Sep 2017 11:17:38 -0600 Subject: vboot: expose vbnv_reset() function It's helpful to use the common vbnv_reset() function to initialize the vbnv contents when backing store failures occur. Therefore, allow that to happen.
