Subject: [PATCH v1] tpm/tpm_ftpm_tee: Use UUID API for exporting the UUID
Date: Wed, 22 Apr 2020 16:01:35 +0300 [thread overview]
Message-ID: <20200422130135.38555-1-andriy.shevchenko@linux.intel.com> (raw)
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.
