Subject: ACPI: utils: include UUID in _DSM evaluation warning
X-Git-Tag: v5.19-rc1~183^2~3
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=06eb8dc097b3fcb2d02eb553b17af5fcc2952f96;p=thirdparty%2Fkernel%2Flinux.git

ACPI: utils: include UUID in _DSM evaluation warning

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)
