| Subject: ACPI: processor: fix acpi_object initialization |
| |
| From: Sebastian Ott <sebott@redhat.com> |
| |
| [ Upstream commit 13edf7539211d8f7d0068ce3ed143005f1da3547 ] |
| |
| Initialization of the local acpi_object in acpi_processor_get_info() |
| only sets the first 4 bytes to zero and is thus incomplete. This is |
| indicated by messages like: |
| acpi ACPI0007:be: Invalid PBLK length [166288104] |
| |
| Fix this by initializing all 16 bytes of the processor member of that |
| union. |
