Subject: tpm/tpm_ftpm_tee: Use UUID API for exporting the UUID
X-Git-Tag: v5.8-rc1~242^2~1
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=8c872863b4400d0c8e31a2ac16389fcaaede5e3c;p=thirdparty%2Fkernel%2Flinux.git

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.
