Upstream PR #3 — kernel per-context vb2_queue lock so concurrent
clients of /dev/video0 don't serialise on a device-wide mutex.
Pi 5 Firefox VAAPI playback (RDD + content + GPU processes each
opening the device) now works without S_FMT EBUSY collisions.
Verified on higgs: YouTube playback engages daedalus at sustained
~230 fps decode through the libavcodec dlopen path, ~7× headroom
over the 30fps@1080p Pi 5 Fourier target.
Both packages: pkgver 0.1.0.r24.f0d4186, pkgrel reset to 1.
