[PATCH 04/15] qemu: Assume QEMU_CAPS_OBJECT_MEMORY_RAM
Michal Privoznik

Thu Nov 3 16:22:02 UTC 2022
Introduced in QEMU's commit of v2.1.0-rc0~41^2~104 the
memory-backend-ram is going to be present for all QEMU versions
we support (4.2.0, currently). Therefore, we can assume the
capability is always set and thus doesn't need to be checked for.
