Thanks @kaihengfeng for the bisection instructions and @jail-j for
pointing me in the right direction. (It's probably worth mentioning that
sudo make -j`nproc` deb-pkg was needed for the build to work)
Here's the most recent result:
git bisect bad
a192aa923b66a435aae56983c4912ee150bc9b32 is the first bad commit

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.

wasn't sure if I'm meant to keep going so I've run sudo make -j`nproc`
deb-pkg again to see what it comes up with.
