Messages in this thread Patch in this message |  | | From | Chen Yu <> | Subject | [PATCH 1/2][RFC] ACPI / PM: Reuse the acpi_sleep_syscore_ops for future requirement | Date | Sat, 26 Aug 2017 00:43:30 +0800 |
| |
There might be other actions to be taken during the acpi syscore suspend/resume phase, thus reuse the acpi_sleep_syscore_ops in case other operations are added into the acpi_sleep_syscore_ops.
No functional change.
