[libcamera-devel] [PATCH 0/4] Fix udev device enumerator with V4L2 M2M devices

[Laurent Pinchart]

Hello,

The latest rework of the udev device enumerator to support delayed
device initialisation broke V4L2 M2M support, as it assumes that a
device node belongs to a single entity. As I'm guilty of having missed
that during review, here's a patch series to fix it.

The first three patches are drive-by cleanups, while the real fix is in
patch 4/4.

Laurent Pinchart (4):
  libcamera: device_enumerator: Move lookupDeviceNode() to child classes
  libcamera: device_enumerator_udev: Delay device node lookup
  libcamera: device_enumerator_udev: Avoid double list lookup
  libcamera: device_enumerator_udev: Support entities sharing device
    nodes
