daedalus-v4l2{,-dkms}: 3dd0eb0 -> 462aa4b — kernel ctrl-binding fix

Browse Source 
Upstream PR #2 landed the one-line kernel fix that was the missing
half of issue libva-v4l2-request-fourier#8: device_run now calls
v4l2_ctrl_request_setup() before reading ctrl->p_cur, so the
daedalus_h264_meta the daemon receives reflects the in-flight
media_request's bound H.264 stateless control values instead of
stale/default ones.

Pairs with libva-v4l2-request-fourier 1.0.0+r382+gc1bb444 (max_num_
ref_frames fallback + Fix 4 instrumentation that exposed the
control-binding gap in the first place).

Effect on Pi 5 / CM5 hosts (higgs): ffmpeg -hwaccel vaapi against
H.264 sources now produces actual decoded content (per-frame
fnv1a hashes differ, zero MB-decode errors) instead of the
constant 0x6a6a05c5 "best-effort give-up" hash and cascading
decode warnings.

Both packages: pkgver 0.1.0.r22.462aa4b, pkgrel reset to 1.

daedalus-v4l2-dkms (0.1.0+r22+g462aa4b-1) bookworm trixie; urgency=medium
* Bump to 462aa4b — kernel device_run() now calls
v4l2_ctrl_request_setup() before reading the H.264 stateless
control values from the bound media_request, so the values
daedalus ships to the userspace daemon match what the V4L2
client (libva-v4l2-request-fourier) actually set. Closes the
libva→kernel control-binding gap that was causing decoded
frames to come back as best-effort zero garbage from libavcodec.
* Wire-ABI lockstep with daedalus-v4l2 0.1.0+r22+g462aa4b.

daedalus-v4l2 (0.1.0+r22+g462aa4b-1) bookworm trixie; urgency=medium
* Bump to 462aa4b — kernel-side fix for control-binding gap that
closes the libva→daemon SPS/PPS pipeline. Kernel device_run now
calls v4l2_ctrl_request_setup() before reading ctrl->p_cur, so
the daemon's daedalus_h264_meta block actually carries THIS
request's V4L2 stateless H.264 control values instead of stale
/default ones. Pairs with libva-v4l2-request-fourier r382+gc1bb444
(Fix 3 + Fix 4 from issue libva-v4l2-request-fourier#8).
* After-fix on higgs (Pi CM5): ffmpeg -hwaccel vaapi -i h264.mp4
produces unique decoded P-frames (per-frame fnv1a hashes differ)
and zero "error while decoding MB" / "reference frames exceeds
max" warnings.
