Convert 'alloc_obj' family to use the new default GFP_KERNEL argument

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: 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: Drop explicit initialization of struct i2c_device_id::driver_data to 0

2024-08-09T05:56:37Z

These drivers don't use the driver_data member of struct i2c_device_id, so don't explicitly initialize this member. This prepares putting driver_data in an anonymous union which requires either no initialization or named designators. But it's also a nice cleanup on its own. While add it, also remove commas after the sentinel entries. Signed-off-by: Uwe Kleine-König Signed-off-by: Hans Verkuil

media: go7007: fix a memleak in go7007_load_encoder

2024-02-28T15:00:33Z

In go7007_load_encoder, bounce(i.e. go->boot_fw), is allocated without a deallocation thereafter. After the following call chain: saa7134_go7007_init |-> go7007_boot_encoder |-> go7007_load_encoder |-> kfree(go) go is freed and thus bounce is leaked.

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.
