If anyone has any objections, please let us know. ------------------ From: Naga Chumbalkar commit 904cc1e637a00dba1b58e7752f485f90ebf2a568 upstream. UUID needs to be written out the way it is described in Sec 18.5.124 of ACPI 4.0a Specification. Platform firmware's use of this UUID/_OSC is optional, which is why we didn't notice this bug earlier.
