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

treewide: Replace kmalloc with kmalloc_obj for non-scalar types

2026-02-21T09:02:28+00:00

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: pci: saa7146: advertise only those TV standard that are supported

2023-04-15T07:56:05+00:00

V4L2_STD_ALL advertises more standards than these boards actually support. This causes a V4L2 compliance issue. Limit the supported standards to those that are actually implemented. Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: mxb: allow tuner/input/audio ioctls for vbi

2023-04-15T07:55:37+00:00

The vbi stream comes from the same video input as the video stream. So all the related ioctls to that are just as valid for the vbi stream. Add these. This fixes a V4L2 compliance issue. Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: mxb: update the tvnorms when changing input

2023-04-15T07:54:58+00:00

The tuner input uses different tvnorms compared to the S-Video/Composite inputs. So update the tvnorms field in struct video_device when switching inputs. This fixes a V4L2 compliance issue. Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: saa7146: convert to vb2

2023-04-15T07:53:31+00:00

Convert this driver from the old videobuf framework to the vb2 frame. Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: saa7146: drop 'dev' and 'resources' from struct saa7146_fh

2023-04-15T07:50:36+00:00

Instead use vv->resources and video_drvdata(file) to obtain this information. This prepares for the vb2 conversion later when saa7146_fh is dropped completely. Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: pci: saa7146: hexium_orion: initialize input 0

2023-04-15T07:49:46+00:00

When this driver is loaded for the first time, input 0 is not initialized. In order to capture from that input you would have to switch to input 1, then back to 0. Properly initialize the input when the driver is loaded. Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: Revert "media: saa7146: deprecate hexium_gemini/orion, mxb and ttpci"

2023-02-09T08:22:36+00:00

This reverts commit e33fdb5a02490059e2f48ced2c038c8a46c6476d. The saa7146-based devices are still in use, esp. for DVB. So move these drivers back to mainline. Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: saa7146: deprecate hexium_gemini/orion, mxb and ttpci

2022-08-29T14:46:38+00:00

Deprecate the hexium_gemini, hexium_orion, mxb and ttpci saa7146-based drivers: these drivers do not use the vb2 framework for video streaming, instead it uses the old videobuf framework. We want to get rid of these old drivers, so deprecated these for future removal. [hverkuil: update MAINTAINERS file] Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab
