Subject: misc/max111x: Create abstract max111x type
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=5ef4a1c304ef60224c29aa9f6d9c2ac0591d020a;p=qemu.git

misc/max111x: Create abstract max111x type

Create an abstract class that encompasses both max111x variants. This is
needed for QOM cast macro creation (and is the right thing to do
anyway). Macroify type-names in the process.
