I'm unable to explicitly verify this, as we don't have any systems that support SDEI - and if we did, they'd probably boot in ACPI mode. I have booted the updated kernel on an arm64 system though, and observed no regressions.

[Test Case] No known test case. [Regression Risk] The code is limited to ARM systems, and the fix is obviously correct (IMO). I'm unaware of any such system in the field - most SDEI-based systems will likely be ACPI based.
