   4 Subject: ACPI: thinkpad-acpi: handle HKEY event 6030
   5
   6 HKEY event 0x6030 is a helper for Lenovo's Advanced Thermal Management
   7 Windows driver, which is, of course, completely undocumented.
   8
   9 Silence any warnings about it being an unknown alarm, and report it
  10 unmodified for userspace.
