[alsa-devel] [PATCH 2/4] acpi: allow for an override to set _REV

>From a Dell perspective I'm not aware of anything else breaking, but I'll be sure to raise its attention and any associated details if I become privy to them.  I'm working with architecture to ensure that future products are not relying on _REV values as well.
I know Matthew had mentioned that another OEM's product was using this as well, but I don't know what for.
