treewide: Replace kmalloc with kmalloc_obj for non-scalar types

2026-02-21T09:02:28Z

This is the result of running the Coccinelle script from scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to avoid scalar types (which need careful case-by-case checking), and instead replace kmalloc-family calls that allocate struct or union object instances: Single allocations: kmalloc(sizeof(TYPE), ...) are replaced with: kmalloc_obj(TYPE, ...) Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...) are replaced with: kmalloc_objs(TYPE, COUNT, ...) Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...) are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...) (where TYPE may also be *VAR) The resulting allocations no longer return "void *", instead returning "TYPE *". Signed-off-by: Kees Cook

media: em28xx: add special case for legacy gpiolib interface

2025-08-29T09:04:02Z

The em28xx driver uses the old-style gpio_request_one() interface to switch the lna on the PCTV 290E card. This interface is becoming optional and should no longer be called by portable drivers. As I could not figure out an obvious replacement, select the new GPIOLIB_LEGACY symbol as a workaround. Signed-off-by: Arnd Bergmann Signed-off-by: Hans Verkuil

media: usb: drop vb2_ops_wait_prepare/finish

2024-10-28T08:19:56Z

Since commit 88785982a19d ("media: vb2: use lock if wait_prepare/finish are NULL") it is no longer needed to set the wait_prepare/finish vb2_ops callbacks as long as the lock field in vb2_queue is set. Since the vb2_ops_wait_prepare/finish callbacks already rely on that field, we can safely drop these callbacks. This simplifies the code and this is a step towards the goal of deleting these callbacks. Signed-off-by: Hans Verkuil

media: em28xx: Set GPIOs for non-audio boards when switching input

2024-06-29T10:20:05Z

Fixes changing the Line Out audio source with the video input on MyGica UTV3 board. Previously, GPIOs were only set in em28xx_set_audio_source(), which only boards with USB audio support reach. Signed-off-by: Nils Rothaug Signed-off-by: Sean Young Signed-off-by: Hans Verkuil

media: em28xx: Add support for MyGica UTV3

2024-06-29T10:20:05Z

The MyGica UTV3 Analog USB2.0 TV Box is a USB video capture card that has analog TV, composite video, and FM radio inputs, an IR remote, and provides audio only as Line Out, but not over USB. Mine is prepared for an FM tuner, but not equipped with one. Support for FM radio is therefore missing. The device contains: - Empia EM2860 USB bridge - Philips SAA7113 video decoder - NXP TDA9801T demodulator - Tena TNF931D-DFDR1 tuner - ST HCF4052 demux, switches input audio to Line Out Signed-off-by: Nils Rothaug Signed-off-by: Sean Young Signed-off-by: Hans Verkuil

media: em28xx: annotate unchecked call to media_device_register()

2024-02-05T11:57:44Z

Static analyzers generate alerts for an unchecked call to `media_device_register()`. However, in this case, the device will work reliably without the media controller API. Add a comment above the call to prevent future unnecessary changes.

media: v4l2-subdev: Turn .[gs]_frame_interval into pad operations

2023-12-13T15:52:35Z

The subdev .[gs]_frame_interval are video operations, but they operate on pads (and even on streams). Not only is this confusing, it causes practical issues for drivers as the operations don't receive a subdev state pointer, requiring manual state handling. To improve the situation, turn the operations into pad operations, and extend them to receive a state pointer like other pad operations. While at it, rename the operations to .[gs]et_frame_interval at the same time to match the naming scheme of other pad operations. This isn't strictly necessary, but given that all drivers using those operations need to be modified, handling the rename separately would generate more churn for very little gain (if at all).

media: v4l: Use correct dependency for camera sensor drivers

2023-09-14T10:38:17Z

The Kconfig option that enables compiling camera sensor drivers is VIDEO_CAMERA_SENSOR rather than MEDIA_CAMERA_SUPPORT as it was previously. Fix this. Also select VIDEO_OV7670 for marvell platform drivers only if MEDIA_SUBDRV_AUTOSELECT and VIDEO_CAMERA_SENSOR are enabled.
