Hello, I'm your host, and it's Sunday, October 25th, 2026.
The lead story today is reliability. Across almost every subsystem merged this week, maintainers tightened who owns a device, where callbacks run, and when resources are freed.
First, lifetime and context safety. In the input merge, tagged a32e63a, the core now rejects parent overrides on managed input devices, so cleanup responsibility isn't split across devices. Related fixes stop reparenting in haptics and touchscreen drivers. Firewire, in merge 065af32, makes a similar guarantee:…
Second, wide new hardware enablement. Media, in merge 42e6549, adds image sensors from Sony, OmniVision, Samsung and Himax, plus Intel I P U 7 and 8, Maxim GMSL serializers, and new capture drivers for NXP, Rockchip and Qualcomm. Sound adds Qualcomm, MediaTek, Airoha and Nvidia machine drivers, plus new codecs and…
Third, shedding legacy. The char misc merge, 330517c, removes the C Binder code now that the Rust version is stable. Staging removes the rtl8723bs Wi-Fi driver, sound removes the obsolete Ux500 machine driver, and S C S I, in merge 6fba331, reworks sense codes to match the 16-bit standard.
What's next: test disconnect, suspend and…
