Smatch is not smart enough to see that "&stream->clock.lock" and "&clock->lock" are the same thing so it complains about the locking here. Let's make it more consistent. Signed-off-by:

V4L2_CID_EXPOSURE_ABSOLUTE property does not return an updated value when autoexposure (V4L2_CID_EXPOSURE_AUTO) is turned on. This patch fixes this issue by adding the UVC_CTRL_FLAG_AUTO_UPDATE flag. Tested on a C920 camera. Signed-off-by:

Smatch complains about where the au8293_data is placed: drivers/media/pci/cx23885/cx23885-dvb.c:2174 dvb_register() info: 'a8293_pdata' is not actually initialized (unreached code). It is not actually expected to have such initialization at switch { foo = bar; case: ... } Not really sure how gcc does that, but this is something that I would expect that different compilers would do different things. David Howells checked with the compiler people: it's not really expected to initialise as expected. So, move the initialization outside the switch(), making smatch to shut up one warning.

The handling of q->plane_sizes was wrong in vb2_core_create_bufs(). The q->plane_sizes array was global and it was overwritten by create_bufs. So if reqbufs was called with e.g. size 100000 then q->plane_sizes[0] would be set to 100000. If create_bufs was called afterwards with size 200000, then q->plane_sizes[0] would be overwritten with the new value. Calling create_bufs again for size 100000 would cause an error since 100000 is now less than q->plane_sizes[0]. This patch fixes this problem by 1) removing q->plane_sizes and using the vb->planes[].length field instead, and 2) by introducing a min_length field in struct vb2_plane. This field is set to the plane size as returned by the queue_setup op and is the minimum required plane size. So user pointers or dmabufs should all be at least this size. Signed-off-by:

Ensure that the offsets are correct before buf_init() is called. As a consequence the __setup_offsets() function now sets up the offsets for the given buffer instead of for all new buffers. Signed-off-by:

Fill in q->bufs[vb->index] before the call to buf_init: it makes sense that this is initialized correctly. Signed-off-by:

Rather than setting up the lengths at the end, set them up when the vb2_buffer is allocated. This also ensures that buf_init() sees the right length values. Signed-off-by:

The timestamp of a v4l2_buffer was advertised as being CLOCK_MONOTONIC, but instead a timestamp from a header field was used. This is inconsistent and not what applications expect. Use v4l2_get_timestamp to properly set the timestamp. Signed-off-by:

During the Seoul media workshop we decided to relax the VIDIOC_CREATE_BUFS specification so it would no longer require drivers to validate the format field since almost no driver did that anyway. Instead drivers use the buffer size(s) based on the format type and the corresponding format fields and will ignore any other fields. If the size cannot be used an error is returned, otherwise the size is used as-is. Signed-off-by:
-
Hans Verkuil authored
The queue_setup callback has a void pointer that is just for V4L2 and is the pointer to the v4l2_format struct that was passed to VIDIOC_CREATE_BUFS. The idea was that drivers would use the information from that struct to buffers suitable for the requested format. After the vb2 split series this pointer is now a void pointer, which is ugly, and the reality is that all existing drivers will effectively just look at the sizeimage field of v4l2_format. To make this more generic the queue_setup callback is changed: the void pointer is dropped, instead if the *num_planes argument is 0, then use the current format size, if it is non-zero, then it contains the number of requested planes and the sizes array contains the requested sizes. If either is unsupported, then return -EINVAL, otherwise use the requested size(s). Signed-off-by:

This is necessary since the *_std_setup functions rely on a valid state->std field. Also fix the cx23888_std_setup() to test for 60Hz instead of NTSC, just like cx25840_std_setup() does. Signed-off-by:

For those two devices the code wrote to addresses 0x115/6, but on those devices those addresses have nothing to do with power controls. So clearly this never worked. Rather than writing to bogus addresses, just do nothing for the cx2388x and cx231xx. Signed-off-by:

The cx23888 reports a slightly different Vsrc value than the other chip variants do. Relax the check by 1, otherwise cx25840_set_fmt() would fail for the cx23888. Signed-off-by:

The cx23888 also moves the following registers around: !cx23888 cx23888 -------- ------- 0x418, 0x41c 0x434, 0x438 0x420 0x418 (expect for bit 29 which has a different meaning) 0x478 0x454 Also drop the set_input code where the scaler is changed: this does not belong here, changing the input should not change the scaler. And that's besides the fact that that code is plain wrong. After this change the cx23888 behaves much better. In particular, calling set_input no longer changes the saturation to 0, causing a grayscale image. Signed-off-by:

While testing the cx23885 driver with various TV standards I found a number of bugs: 1) norm_maxw() returned 768 instead of 720 for PAL formats. This should always be 720, so drop this inline function and just always use 720. 2) cropcap() was missing, so the pixelaspect was never known and qv4l2 would scale the image incorrectly. Add cropcap support. 3) cx23885_set_tvnorm() should just return 0 if the same standard was set again. If another standard is set, then reset the width/height and call set_fmt for the subdevs. Signed-off-by:

'struct timeval tv' and 'struct timeval now' is used to calculate the elapsed time. 'LIRC_SFH506_DELAY' is a delay t_phl in usecs. 32-bit systems using 'struct timeval' will break in the year 2038, so we have to replace that code with more appropriate types. This patch changes the lirc_parallel.c file of media: lirc driver to use ktime_t. ktime_get() is better than using do_gettimeofday(), because it uses the monotonic clock. ktime_sub is used to subtract two ktime variables. ktime_to_us() is used to convert ktime to microsecond. New ktime_t variable timeout, is added in lirc_off(),to improve clarity. Introduced a new ktime_t variable in lirc_lirc_irq_handler() function, to avoid the use of signal variable for storing seconds in the first part of this function as later it uses a time unit that is defined by the global "timer" variable. This makes it more clear. ktime_set() is used to set a value in seconds to a value in nanosecond so that ktime_compare() can be used appropriately. ktime_compare() is used to compare two ktime values. ktime_add_ns() is used to increment a ktime value by 1 sec. One comment is also shifted a line up, as it was creating a 80 character warning. Build tested it. Also tested it with sparse. Signed-off-by:

'struct timeval presstime' and 'struct timeval tv' is used to calculate the time since the last button press. 32-bit systems using 'struct timeval' will break in the year 2038, so we have to replace that code with more appropriate types. This patch changes the media: lirc driver to use ktime_t. ktime_get() is better than using do_gettimeofday(), because it uses the monotonic clock. ktime_sub() are used to subtract two ktime variables. 'ms' is only used to check how much time has passed by comparing to 250. So instead of using expensive ktime_to_ms() call, it has been changed to hold nanoseconds by using ktime_to_ns(). Build tested it. Tested with sparse too. Signed-off-by:

'struct timeval tv' is used to get current time. 'static struct timeval lasttv' is used to get last interrupt time. 32-bit systems using 'struct timeval' will break in the year 2038, so we have to replace that code with more appropriate types. This patch changes the lirc_serial.c file of media: lirc to use ktime_t. ktime_get() is better than using do_gettimeofday(), because it uses the monotonic clock. ktime_sub is used to subtract two ktime variables. The check to test time going backwards is also removed. Intialization to static variable is also removed. ktime_to_us() is used to convert ktime_t to microsecond value. deltv is changed to delkt, a ktime_t type varibale from long to assign the ktime_sub value directly. ktime_compare is used to compare delkt with 15 seconds, which is changed to a nanosecond value by using ktime_set(). Build tested it. Signed-off-by:
