Comparing an int to a size, which is unsigned, causes the int to become unsigned, giving the wrong result. kinect_read returns the result of usb_control_msg, which can return a negtive error code. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ int x; expression e,e1; identifier f; @@ *x = f(...); ... when != x = e1 when != if (x < 0 || ...) { ... return ...; } *x < sizeof(e) // </smpl> Signed-off-by:

The error path currently calls tw686x_video_free() which requires vc->dev to be initialized, causing a NULL dereference on uninitizalized channels. Fix this by setting the vc->dev fields for all the channels first. Fixes: f8afaa8d ("[media] tw686x: Introduce an interface to support multiple DMA modes") Signed-off-by:

The use of 'DTV' is very confusing since it normally refers to Digital TV e.g. DVB etc. Instead use 'DV' (Digital Video), which nicely corresponds to the DV Timings API used to configure such receivers and transmitters. We keep an alias to avoid breaking userspace applications. Since this alias is only available if __KERNEL__ is *not* defined (i.e. it is only available for userspace, not kernelspace), any drivers that use it also have to be converted to the new define. These drivers are adv7604, adv7842 and tda1997x. Signed-off-by:

The v2 entity structure never exposed the entity flags, which made it impossible to detect connector or default entities. It is really trivial to just expose this information, so implement this. Signed-off-by:

Commit 1d389714 ("[media] v4l: rcar_fdp1: add FCP dependency") fixed a compilation breakage when the optional VIDEO_RENESAS_FCP dependency is compiled as a module while the rcar_fdp1 driver is built in. As a side effect it disabled compilation on Gen2 by disallowing the valid combination ARCH_RENESAS && !VIDEO_RENESAS_FCP. Fix it by handling the dependency the same way the vsp1 driver did in commit 19994673 ("[media] vsp1: clarify FCP dependency").

The vb2_core_qbuf() function didn't check if q->error was set. It is checked in __buf_prepare(), but that function isn't called if the buffer was already prepared before with VIDIOC_PREPARE_BUF. So check it at the start of vb2_core_qbuf() as well. Signed-off-by:

Implementing job_abort() does not make sense on some drivers. This is not a problem, as the abort is not required to wait for the job to finish. Quite the opposite, drivers are encouraged not to wait. Demote v4l2_m2m_ops.job_abort from required to optional, and clean all drivers with dummy implementations. Signed-off-by:

As per the documentation, job_abort is not required to wait until the current job finishes. It is redundant to do so, as the core will perform the wait operation. Remove the wait infrastructure completely. Signed-off-by:
