The VIDIOC_G/S_EDID ioctls can return valid data even if an error is returned. Mark those ioctls accordingly. Rather than using an explicit 'if' to check for the ioctl (as was done until now for VIDIOC_QUERY_DV_TIMINGS) just set a new flag in the v4l2_ioctls array. Signed-off-by:

In 'commit 295ab497 ("[media] media: platform: pxa_camera: make printk consistent")' a pointer to the device structure in mclk_get_divisor() was changed to pcdev_to_dev(pcdev). The pointer used by pcdev_to_dev() is still uninitialized during the call to mclk_get_divisor() as it happens in v4l2_device_register() at the end of the probe. The dev_warn and dev_dbg caused a line in the log: (NULL device *): Limiting master clock to 26000000 Fix this by using an initialized pointer from the platform_device (as before the old patch).

During the transfer from the soc_camera a test in pxa_mbus_image_size() got removed. Without it any PXA_MBUS_LAYOUT_PACKED format causes either the return of a wrong value (PXA_MBUS_PACKING_2X8_PADHI doubles the correct value) or EINVAL (PXA_MBUS_PACKING_NONE and PXA_MBUS_PACKING_EXTEND16). This was observed in an error from the ffmpeg (for some of the YUYV subvariants). This patch re-adds the same test as in soc_camera version. Signed-off-by:

This patch adds Bayer 8 GBRG and RGGB support and move GRBG definition close to BGGR (so all Bayer 8 variants are together). No other changes are needed as the driver handles them as RAW data stream. The RGGB variant was tested in a modified OV9640 driver. Signed-off-by:

Permits distinguishing between two /dev/videoX entries from the same physical UVC device (that naturally share the same iProduct name). This change matches current Windows behavior by prioritizing iFunction over iInterface, but unlike Windows it displays both iProduct and iFunction/iInterface strings when both are available.

The recent changes in 4.9 to mandate USB buffers be heap allocated broke this driver, which was allocating the buffers on the stack. This resulted in the device failing at initialization. Introduce dedicated send/receive buffers as part of the state structure, and add a mutex to protect access to them. Note: we also had to tweak the API to mxl111sf_ctrl_msg to pass the pointer to the state struct rather than the device, since we need it inside the function to access the buffers and the mutex. This patch adjusts the callers to match the API change. Signed-off-by:

Setting initial standard at the top of cx8800_initdev would cause the first call to cx88_set_tvnorm() to return without programming any registers (leaving the driver saying it's set to NTSC but the hardware isn't programmed). Even worse, any subsequent attempt to explicitly set it to NTSC-M will return success but actually fail to program the underlying registers unless first changing the standard to something other than NTSC-M. Set the initial standard later in the process, and make sure the field is zero at the beginning to ensure that the call always goes through. This regression was introduced in the following commit: commit ccd6f1d4 ("[media] cx88: move width, height and field to core struct") Author: Hans Verkuil <hans.verkuil@cisco.com> [media] cx88: move width, height and field to core struct Signed-off-by:

Without annotations, gcc 7.1 will complain. Signed-off-by: -
Mauro Carvalho Chehab authored
On this driver, it can fall through a switch. I tried to annotate it, in order to shut up a gcc warning, but that didn't work, as the logic there is somewhat complex. So, instead, let's just repeat the code. gcc should likely optimize it anyway, and this makes the code better readable, IMHO. Signed-off-by: -

On two switches, this driver have unannotated switch fall through. in the first case, it falls through a return. On the second one, it prints undesired log messages on fall through. Solve that by copying the commands that it should be running. Gcc will very likely optimize it anyway, so this sholdn't be causing any harm, and shuts up gcc warnings. Signed-off-by: -

The atomisp currently produce hundreds of warnings when W=1. It is a known fact that this driver is currently in bad shape, and there are lot of things to be done here. We don't want to be bothered by those "minor" stuff for now, while the driver doesn't receive a major cleanup. So, disable those warnings. Signed-off-by: -

With gcc-7.1.1 I was getting the following compile error: error: ‘*’ in boolean context, suggest ‘&&’ instead The problem is the definition of CEIL_DIV: #define CEIL_DIV(a, b) ((b) ? ((a) + (b) - 1) / (b) : 0) Which when called as: CEIL_DIV(x, y * z) triggers this error, note we cannot do as the error suggests since b is evaluated multiple times.
