When user space queues a buffer using VIDIOC_QBUF, the kernel
should set flags in struct v4l2_buffer as specified in the V4L2
documentation.

Hi, quoting V4L2 spec:
http://v4l2spec.bytesex.org/spec/r13317.htm
"__s32 step
[...]
Generally drivers should not scale hardware control values. It may be
necessary for example when the name or id imply a particular unit and the
hardware actually accepts only multiples of said unit. If so, driv
When user space queues a buffer using VIDIOC_QBUF, the kernel
should set flags to V4L2_BUF_FLAG_QUEUED in struct v4l2_buffer.
videobuf_qbuf() was missing a call to videobuf_status() which does
that. This patch adds the proper function call.

Hi,
I am writing a generic driver for SMIA-compatible sensors.
SMIA-sensors have registers containing:
u16 model_id
u16 revision_number
u8 manufacturer_id
which could be used to detect the sensor.
However, since the driver is generic, it is not interested
of these values.
Nevertheless, in s
