Further local variables have been removed as they became unused as a result of the other changes. Also Coccinelle introduced indentation by space in files drivers/media/i2c/st-mipid02.c and drivers/media/platform/rockchip/rkisp1/rkisp1-isp.c. This has been also corrected.

* media: Switch i2c drivers back to use .probe()Uwe Kleine-König2023-05-251-1/+1
| | | | | | | | | | | After commit b8a1a4cd5a98 ("i2c: Provide a temporary .probe_new() call-back type"), all drivers being converted to .probe_new() and then commit 03c835f498b5 ("i2c: Switch .probe() to not take an id parameter") convert back to (the new) .probe() to be able to eventually drop .probe_new() from struct i2c_driver.

* i2c: Make remove callback return voidUwe Kleine-König2022-08-161-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The value returned by an i2c driver's remove function is mostly ignored. (Only an error message is printed if the value is non-zero that the error is ignored.) So change the prototype of the remove function to return no value. This way driver authors are not tempted to assume that passing an error to the upper layer is a good idea. All drivers are adapted accordingly. There is no intended change of behaviour, all callbacks were prepared to return 0 before.

I was working on subdev internal routing between pads, and realized that there's no way to add TRY functionality for routes, which is not pad specific configuration. Adding a separate struct for try-route config wouldn't work either, as e.g. set-fmt needs to know the try-route configuration to propagate the settings. This patch adds a new struct, 'struct v4l2_subdev_state' (which at the moment only contains the v4l2_subdev_pad_config array) and the new struct is used in most of the places where v4l2_subdev_pad_config was used. All v4l2_subdev_pad_ops functions taking v4l2_subdev_pad_config are changed to instead take v4l2_subdev_state. The changes to drivers/media/v4l2-core/v4l2-subdev.c and include/media/v4l2-subdev.h were written by hand, and all the driver changes were done with the semantic patch below. The spatch needs to be applied to a select list of directories. I used the following shell commands to apply the spatch: dirs="drivers/media/i2c drivers/media/platform drivers/media/usb drivers/media/test-drivers/vimc drivers/media/pci drivers/staging/media" for dir in $dirs; do spatch -j8 --dir --include-headers --no-show-diff --in-place --sp-file v4l2-subdev-state.cocci $dir; done Note that Coccinelle chokes on a few drivers (gcc extensions?). With minor changes we can make Coccinelle run fine, and these changes can be reverted after spatch.

* [media] media framework: rename pads init function to media_entity_pads_init()Mauro Carvalho Chehab2016-01-111-1/+1
| | | | | | | | | | | | | | | | | With the MC next gen rework, what's left for media_entity_init() is to just initialize the PADs. However, certain devices, like a FLASH led/light doesn't have any input or output PAD. So, there's no reason why calling media_entity_init() would be mandatory. Also, despite its name, what this function actually does is to initialize the PADs data. So, rename it to media_entity_pads_init() in order to reflect that. The media entity actual init happens during entity register, at media_device_register_entity(). We should move init of num_links and num_backlinks to it.

* [media] media: get rid of unused "extra_links" param on media_entity_init()Mauro Carvalho Chehab2016-01-111-1/+1
| | | | | | | | | | | | | | | | | | Currently, media_entity_init() creates an array with the links, allocated at init time. It provides a parameter (extra_links) that would allocate more links than the current needs, but this is not used by any driver. As we want to be able to do dynamic link allocation/removal, we'll need to change the implementation of the links. So, before doing that, let's first remove that extra unused parameter, in order to cleanup the interface first.

* [media] v4l2-subdev: replace v4l2_subdev_fh by v4l2_subdev_pad_configHans Verkuil2015-03-231-9/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If a subdevice pad op is called from a bridge driver, then there is no v4l2_subdev_fh struct that can be passed to the subdevice. This made it hard to use such subdevs from a bridge driver. This patch replaces the v4l2_subdev_fh pointer by a v4l2_subdev_pad_config pointer in the pad ops. This allows bridge drivers to use the various try_ pad ops by creating a v4l2_subdev_pad_config struct and passing it along to the pad op. The v4l2_subdev_get_try_* macros had to be changed because of this, so I also took the opportunity to use the full name of the v4l2_subdev_get_try_* functions in the __V4L2_SUBDEV_MK_GET_TRY macro arguments: if you now do 'git grep v4l2_subdev_get_try_format' you will actually find the header where it is defined. One remark regarding the drivers/staging/media/davinci_vpfe patches: the *_init_formats() functions assumed that fh could be NULL. However, that's not true for this driver, it's always set. This is almost certainly a copy and paste from the omap3isp driver. I've updated the code to reflect the fact that fh is never NULL.

This patch adds subdev driver for Samsung S5K6A3 raw image sensor. As it is intended at the moment to be used only with the Exynos FIMC-IS (camera ISP) subsystem it is pretty minimal subdev driver. It doesn't do any I2C communication since the sensor is controlled by the ISP and its own firmware. This driver, if needed, can be updated in future into a regular subdev driver where the main CPU communicates with the sensor directly.
