Subject: [PATCH v1 1/4] hyper-v: Use UUID API for exporting the GUID (part 2)
Date: Thu, 23 Apr 2020 16:45:02 +0300	[thread overview]
Message-ID: <20200423134505.78221-1-andriy.shevchenko@linux.intel.com> (raw)

This is a follow up to the commit 1d3c9c075462
  ("hyper-v: Use UUID API for exporting the GUID")
which starts the conversion.

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.
