From 8c872863b4400d0c8e31a2ac16389fcaaede5e3c Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Wed, 22 Apr 2020 16:01:35 +0300 Subject: [PATCH] tpm/tpm_ftpm_tee: Use UUID API for exporting the UUID There is export_uuid() function which exports uuid_t to the u8 array. Use it instead of open coding variant. This allows to hide the uuid_t internals.
