Patch-mainline: v5.7-rc4
Subject: hyper-v: Use UUID API for exporting the GUID
Git-commit: 1d3c9c075462e9c5a474248e4b433861572f33e9
References: jsc#sle-12891

There is export_guid() function which exports guid_t to the u8 array.
Use it instead of open coding variant.

This allows to hide the uuid_t internals.
