You're right, thanks. Exposing rkvenc0/rkvenc1 as two nodes and pushing
the core choice onto userspace is backwards; rkvdec_disable_multicore()
is the pattern to follow -- probe only the first core, keep any
multi-core scheduling inside the driver. I'll fix that.

Depending on where the interface discussion in the 0/3 thread lands
(Nicolas is pointing at a lower-level stateless / Vulkan-Video direction
that Detlev is already building for RK3588) this driver's shape may
change quite a bit, but the "don't offload core selection to userspace"
point holds either way.

Thanks,
Jiaxing
