* media: imx274: Silence uninitialized variable warningDan Carpenter2018-01-051-1/+1
| | | | | | | | | | | Smatch complains that "err" can be uninitialized if we have a zero size write. The flow analysis is a little complicated so I'm not sure if that's possible or not, but it's harmless to set this to zero and it makes the code easier to read.

* media: i2c: as3645a: Remove driverSakari Ailus2017-12-293-889/+0
| | | | | | | | | | | Remove the V4L2 AS3645A sub-device driver in favour of the LED flash class driver for the same hardware, drivers/leds/leds-as3645a.c. The latter uses the V4L2 flash LED class framework to provide V4L2 sub-device interface.

* media: get rid of i2c-addr.hMauro Carvalho Chehab2017-12-182-3/+0
| | | | | | | | | | In the past, the same I2C address were used on multiple places. After I2C rebinding changes, this is no longer needed. So, we can just get rid of this header, placing the I2C address where they belong, e. g. either at bttv driver or at tvtuner.

* media: i2c: enable i2c IR for hardware which isn't HD-PVRSean Young2017-12-141-0/+9
| | | | | | | | | | | | | | | This is a fix for commit 329d88da4df9 ("[media] media: i2c: Don't export ir-kbd-i2c module alias") that stopped the module from being loaded automagically. The problems described only affect the HD-PVR, so it should not affect other hardware; also if the module happens to be loaded, the i2c IR part of the HD-PVR will be enabled anyway.

* media: rc: implement zilog transmitterSean Young2017-12-141-8/+428
| | | | | | | | | | | | | | | | This code implements the transmitter which is currently implemented in the staging lirc_zilog driver. The new code does not need a signal database, iow. the haup-ir-blaster.bin firmware file is no longer needed, and the driver does not know anything about the keycodes in that file. Instead, the new driver can send raw IR, but the hardware is limited to few different lengths of pulse and spaces, so it is best to use generated IR rather than recorded IR.

* media: merge ir_tx_z8f0811_haup and ir_rx_z8f0811_haup i2c devicesSean Young2017-12-141-2/+2
| | | | | | | | | | | | These two devices ids are really just one device with multiple addresses. Probing becomes much simpler if we simply fold this into one i2c device with two address. Note that this breaks the lirc_zilog driver, however we will teach ir-kbd-i2c to do what lirc_zilog does in a later commit.

* media: imx274: don't randomly return if range_count is zeroMauro Carvalho Chehab2017-12-111-0/+2
| | | | | | | | | | | | | | | | | | | | As smatch reported: drivers/media/i2c/imx274.c:659 imx274_regmap_util_write_table_8() error: uninitialized symbol 'err'. There is a bug at imx274_regmap_util_write_table_8() with causes it to randomly return a random error if range_count is zero. Worse than that, the logic there starts with range_count equal to zero, and periodically resets it to zero again. As it is a way more likely that err assumes a non-zero value, I suspect that the chance of this code to run is very small, so, it would be worth to review the entire function. Anyway, clearly it shouldn't be returning error if range_count is zero. So, let's fix it. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>

These types devices aren't directly related to the sensor, but are nevertheless handled by the smiapp driver due to the relationship of these component to the main part of the camera module --- the sensor. This does not yet address providing the user space with information on how to associate the sensor or lens devices but the kernel now has the necessary information to do that.

| * media: ov9650: remove unnecessary terminated entry in menu items arrayAkinobu Mita2017-10-311-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The test_pattern_menu[] array has two valid items and a null terminated item. So the control's maximum value which is passed to v4l2_ctrl_new_std_menu_items() should be one. However, 'ARRAY_SIZE(test_pattern_menu) - 1' is actually passed and it's not correct. Fix it by removing unnecessary terminated entry and let the correct control's maximum value be passed to v4l2_ctrl_new_std_menu_items().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The v4l2_i2c_subdev_init() sets V4L2_SUBDEV_FL_IS_I2C flag in the subdev->flags. But this driver overwrites subdev->flags immediately after calling v4l2_i2c_subdev_init(). So V4L2_SUBDEV_FL_IS_I2C is not set after all. This stops breaking subdev->flags and preserves V4L2_SUBDEV_FL_IS_I2C. Side note: According to the comment in v4l2_device_unregister(), this is problematic only if the device is platform bus device.
