This has been on my TODO list for some time now: the control that enables the video loopback was part of the controls of the video output device instead of the video capture device. In practice this was quite annoying since you expect it at the capture side since that's where you want to make the decision whether to use the TPG or looped video. This patch moves the control from the output to the capture side. Signed-off-by:

The tuner FMD1216ME_MK3 suffers the same problem as FMD1216MEX_MK3, as described in saa7134-cards.c (disabled IF, enabled DVB-T). The card does work under MS Windows, after soft reboot into Linux it continues to work, only then tda9887 is loaded as well. I copied the relevant code from the BEHOLD_H6 section to MD7134. The CTX946 TV card doesn't detect a signal after cold boot, seems Signed-off-by:

Current v4l2_of_parse_parallel_bus function attempts to parse the DT properties for the parallel bus as well as BT656 bus. If the pclk-sample property is defined for the BT656 bus, it is still marked as a parallel bus. Fix this by parsing the pclk after the bus_type is selected. Only when hsync or vsync properties are specified, the bus_type should be set to V4L2_MBUS_PARALLEL. Signed-off-by:

Commit 84cb7be4 broke vivid-tpg (uninitialized variable p). This patch takes a different approach: four different functions are created, one for each PRINTSTR version. In order to avoid the 'the frame size of 1308 bytes is larger than 1024 bytes' warning I had to mark those functions with 'noinline'. For whatever reason gcc seems to inline this aggressively and it is doing weird things with the stack. I tried to read the assembly code, but I couldn't see what exactly it was doing on the stack.

Document the new Transfer Function control (and fix the documentation for the other colorspace controls which were not quite correct). Mention the support for 4:2:0 and more multiplanar formats. Update the TODO list at the end. Signed-off-by:

Simplify cobalt_g/try_fmt_vid_cap by not setting the colorspace fields in pix again (since v4l2_fill_pix_format does that already), and by using v4l2_fill_mbus_format in cobalt_s_fmt_vid_out which allows the get_fmt call to be dropped as well. Signed-off-by:

-
Hans Verkuil authored
In the past the transfer function was implied by the colorspace. However, it is an independent entity in its own right. Add support for explicitly choosing the transfer function. This change will allow us to represent linear RGB (as is used by openGL), and it will make it easier to work with decoded video material since most codecs store the transfer function as a separate property as well.

Instead of using a state machine and a switch with lots of fall-trough, use gotos and cleanup the error handling loop. That removes those two smatch warnings: drivers/staging/media/lirc/lirc_imon.c:933 imon_probe() warn: possible memory leak of 'context' drivers/staging/media/lirc/lirc_imon.c:933 imon_probe() warn: possible memory leak of 'driver' And make the error handling code more standard.

Smatch reports a warning: drivers/media/usb/tm6000/tm6000-video.c:646 tm6000_prepare_isoc() error: we previously assumed 'dev->urb_buffer' could be null (see line 624) This is not really a problem, but it actually shows that the check if urb_buffer is NULL is being done twice: at the if and at tm6000_alloc_urb_buffers(). We don't need to do it twice. So, remove the extra check. The code become cleaner, and, as a collateral effect, smatch becomes happy. Signed-off-by: -

As reported by smatch: drivers/media/pci/bt8xx/dst_ca.c:323 ca_get_message() warn: this array is probably non-NULL. 'p_ca_message->msg' drivers/media/pci/bt8xx/dst_ca.c:498 ca_send_message() warn: this array is probably non-NULL. 'p_ca_message->msg' Those two checks are needless/useless, as the ca_msg struct is declared as: typedef struct ca_msg { unsigned int index; unsigned int type; unsigned int length; unsigned char msg[256]; } ca_msg_t; So, if the p_ca_message pointer is not null, msg will also be not null.

Smatch reports two issues: drivers/media/platform/sh_vou.c:670 vou_adjust_output() error: buffer overflow 'vou_scale_v_num' 3 <= 4 drivers/media/platform/sh_vou.c:670 vou_adjust_output() error: buffer overflow 'vou_scale_v_den' 3 <= 4 It seems that there's actually a bug here: the same var (idx) is used as an index for vertical and horizontal scaling arrays. However, there are 4 elements on the h arrays, and only 3 at the v ones. On the first loop, it may select index 4 for the horizontal array. In this case, if the second loop fails to select an index, the code would keep using 4 for the vertical array, with is past of the array sizes. The intent here seems to use index 0, if the scale is not found. So, use a separate var for the vertical index. Signed-off-by: -

Commits a0f10c13 and 6c9fe765 ("media: s5p-mfc: fix broken pointer cast on 64bit arch") fixed issue with lossy cast on 64-bit architectures. However it also removed __iomem attribute from that cast. This leads to sparse warnings. This patch fixes those warnings by adding __iomem cast in case of v6+ code version and replacing readl/writel by simple u32 load/store operations in case of v5 code (which is called on system memory allocated by dma_alloc_coherent() instead of io registers).
