Subject: [PATCH] ACPI: utils: include UUID in _DSM evaluation warning
Date: Mon, 16 May 2022 19:25:37 +0200	[thread overview]
Message-ID: <f80dfd57fdca87897f070a3ea4ee0a26b03e7831.camel@mniewoehner.de> (raw)

The _DSM evaluation warning in its current form is not very helpful, as 
it lacks any specific information:
  ACPI: \: failed to evaluate _DSM (0x1001)

Thus, include the UUID of the missing _DSM:
  ACPI: \: failed to evaluate _DSM bf0212f2-... (0x1001)
