[libcamera-devel] [PATCH v1 1/5] v4l2: v4l2_compat_manager: Print path and fd in openat()

[Laurent Pinchart]

The V4L2 compat layer prints debug messages that mention the file
descriptor of the video device, but no message that links the device
path to the file descriptor. Fix it by adding a debug message in
openat().
