As reported by gcc: + drivers/staging/media/imx/imx-media-csi.c: warning: variable 'input_fi' set but not used [-Wunused-but-set-variable]: => 671:33 + drivers/staging/media/imx/imx-media-csi.c: warning: variable 'pinctrl' set but not used [-Wunused-but-set-variable]: => 1742:18 input_fi is not used, so just remove it. However, pinctrl should be used, as it devm_pinctrl_get_select_default() is declared with attribute warn_unused_result. What's missing there is an error handling code, in case it fails. Add it.

The ADV748x handles interlaced media using V4L2_FIELD_ALTERNATE field types. The correct specification for the height on the mbus is the image height, in this instance, the field height. The AFE component already correctly adjusts the height on the mbus, but the HDMI component got left behind. Adjust the mbus height to correctly describe the image height of the fields when processing interlaced video for HDMI pipelines.

The v4l2_mbus_fmt width and height corresponds directly with the v4l2_pix_format definitions, yet the differences in documentation make it ambiguous what to do in the event of field heights. Clarify this using the same text as is provided for the v4l2_pix_format which is explicit on the matter, and by matching the terminology of 'image height' rather than the misleading 'frame height'.

cec_transmit_msg_fh() first checked the message for errors, and only after the message was found to be valid did it log the message contents. However, that makes it hard to associate an error in the kernel log with the message since the message contents was never logged in that case. So swap the order: first log the message (once some very basic checks are done), and only after that check for errors. Signed-off-by:

Add suffix ULL to constant 10 in order to give the compiler complete information about the proper arithmetic to use. Notice that this constant is used in a context that expects an expression of type u64 (64 bits, unsigned). The expression len * 10 * CEC_TIM_DATA_BIT_TOTAL is currently being evaluated using 32-bit arithmetic. Also, remove unnecessary parentheses and add a code comment to make it clear what is the reason of the code change.

Fixes vb2_vmalloc_get_userptr() to ioremap correct area. Since the current code does ioremap the page address, if the offset > 0, it does not do ioremap the last page and results in kernel panic. This fixes to pass the size + offset to ioremap so that ioremap can map correct area. Also, this uses __pfn_to_phys() to get the physical address of given PFN. Signed-off-by:

If buffers were prepared or queued and the buffers were released without starting the queue, the finish mem op (corresponding to the prepare mem op) was never called to the buffers. Before commit a136f59c there was no need to do this as in such a case the prepare mem op had not been called yet. Address the problem by explicitly calling finish mem op when the queue is stopped if the buffer is in either prepared or queued state.

Currently an out of range dev->nr is detected by just reporting the issue and later on an out-of-bounds read on array card occurs because of this. Fix this by checking the upper range of dev->nr with the size of array card (removes the hard coded size), move this check earlier and also exit with the error -ENOSYS to avoid the later out-of-bounds array read.

A recent change to the media_entity_to_video_device() macro breaks some use-cases for the macro due to a symbol collision. Before the change this worked: vdev = media_entity_to_video_device(link->sink->entity); While after the change it results in a compiler error "error: 'struct video_device' has no member named 'link'; did you mean 'lock'?". While the following still works after the change. struct media_entity *entity = link->sink->entity; vdev = media_entity_to_video_device(entity); Fix the collision by renaming the macro argument to '__entity'.

Quoting the original report: It looks like there is a double-free vulnerability in Linux usbtv driver on an error path of usbtv_probe function. When audio registration fails, usbtv_video_free function ends up freeing usbtv data structure, which gets freed the second time under usbtv_video_fail label. usbtv_audio_fail: usbtv_video_free(usbtv); => v4l2_device_put(&usbtv->v4l2_dev); => v4l2_device_put => kref_put => v4l2_device_release => usbtv_release (CALLBACK) => kfree(usbtv) (1st time) usbtv_video_fail: usb_set_intfdata(intf, NULL); usb_put_dev(usbtv->udev); kfree(usbtv); (2nd time) So, as we have refcounting, use it Reported-by:Yavuz, Tuba <tuba@ece.ufl.edu> Signed-off-by:

While the h.264 standard only allows up to 16 reference frames, the CODA firmware needs two more buffers: one to hold the currently decoded frame and one for the display frame. Adding the framebuffer needed by the driver for VDOA operation brings the total to a maximum of 19 internal framebuffers. Lift the current maximum of 17 internal framebuffers to allow playback of high profile streams that require more than 14 reference frames. Signed-off-by:
