| 4 | Subject: [CPUFREQ] Fix _OSC UUID in pcc-cpufreq | |
| 5 | ||
| 6 | From: Naga Chumbalkar <nagananda.chumbalkar@hp.com> | |

| 8 | commit 904cc1e637a00dba1b58e7752f485f90ebf2a568 upstream. | |
| 9 | ||
| 10 | UUID needs to be written out the way it is described in | |
| 11 | Sec 18.5.124 of ACPI 4.0a Specification. | |
| 12 | ||
| 13 | Platform firmware's use of this UUID/_OSC is optional, which is | |
| 14 | why we didn't notice this bug earlier. | |
