ACPI / LPSS: Consolidate runtime PM and system sleep handling
Move the LPSS-specific code from acpi_lpss_runtime_suspend()
and acpi_lpss_runtime_resume() into separate functions,
acpi_lpss_suspend() and acpi_lpss_resume(), respectively, and
make acpi_lpss_suspend_late() and acpi_lpss_resume_early() use
them too in order to unify the runtime PM and system sleep
handling in the LPSS driver.

- from an email list I saw that @kaihengfeng has contacted a kernel.org developer who has written a patch to test.
- I don't know if I'm supposed to test this patch (i might just be added to the email list because I opened this bug report) or whether Kai-Heng Feng will post here to let others try a kernel with the patch applied and see if it works.
Here's a more succinct update of how things seem to be progressing:
- There's a bugzilla.kernel.org bug report that describes this same behaviour: https:/ /bugzilla. kernel. org/show_ bug.cgi? id=199025
