Subject: [PATCH v2 4/5] ACPI / extlog: Switch to use new generic UUID API
Date: Wed, 31 May 2017 22:41:51 +0300	[thread overview]
Message-ID: <20170531194152.65927-5-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <20170531194152.65927-1-andriy.shevchenko@linux.intel.com>

There are new types and helpers that are supposed to be used in new code.

As a preparation to get rid of legacy types and API functions do
the conversion here.
