media: vimc: Fix wrong function called when vimc_init() fails

2023-01-14T09:15:32+00:00

[ Upstream commit f74d3f326d1d5b8951ce263c59a121ecfa65e7c0 ] In vimc_init(), when platform_driver_register(&vimc_pdrv) fails, platform_driver_unregister(&vimc_pdrv) is wrongly called rather than platform_device_unregister(&vimc_pdev), which causes kernel warning: Unexpected driver unregister! WARNING: CPU: 1 PID: 14517 at drivers/base/driver.c:270 driver_unregister+0x8f/0xb0 RIP: 0010:driver_unregister+0x8f/0xb0 Call Trace: vimc_init+0x7d/0x1000 [vimc] do_one_initcall+0xd0/0x4e0 do_init_module+0x1cf/0x6b0 load_module+0x65c2/0x7820 Fixes: 4a29b7090749 ("[media] vimc: Subdevices as modules") Signed-off-by: Chen Zhongjin Signed-off-by: Shuah Khan Signed-off-by: Mauro Carvalho Chehab Signed-off-by: Sasha Levin

media: media/test-drivers: use vb2_video_unregister_device()

2020-08-28T13:05:40+00:00

Use vb2_video_unregister_device() to automatically stop streaming at unregister time. This avoids the use of vb2_queue_release() which should not be called by drivers that set vdev->queue. Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: vimc: cap: Report a colorspace

2020-04-29T10:02:30+00:00

The colorspace reported by a video nodes should not be V4L2_COLORSPACE_DEFAULT. Instead a default colorspace should be picked by the driver if V4L2_COLORSPACE_DEFAULT is given by userspace to {G,S,TRY}_FMT. The colorspace V4L2_COLORSPACE_SRGB is arbitrary chosen as the vimc default format to report as it's used for most webcams.
