2021-11-19T06:05:12Z

USB control-message timeouts are specified in milliseconds and should specifically not vary with CONFIG_HZ.

media: cpia2: fix memory leak in cpia2_usb_probe

2021-05-19T07:51:39Z

syzbot reported leak in cpia2 usb driver. The problem was in invalid error handling. v4l2_device_register() is called in cpia2_init_camera_struct(), but all error cases after cpia2_init_camera_struct() did not call the v4l2_device_unregister() Reported-by: syzbot+d1e69c888f0d3866ead4@syzkaller.appspotmail.com Signed-off-by: Pavel Skripkin Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

module: remove never implemented MODULE_SUPPORTED_DEVICE

2021-03-17T20:16:18Z

MODULE_SUPPORTED_DEVICE was added in pre-git era and never was implemented. We can safely remove it, because the kernel has grown to have many more reliable mechanisms to determine if device is supported or not. Signed-off-by: Leon Romanovsky Signed-off-by: Linus Torvalds

treewide: Use fallthrough pseudo-keyword

2020-08-23T22:36:59Z

Replace the existing /* fall through */ comments and its variants with the new pseudo-keyword macro fallthrough[1]. Also, remove unnecessary fall-through markings when it is the case.

media: media/usb: rename VFL_TYPE_GRABBER to _VIDEO

2020-02-24T15:53:16Z

'GRABBER' is a weird name, all other types map to the /dev device names. Rename to 'VIDEO' to be consistent with the other types. Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: v4l2: abstract timeval handling in v4l2_buffer

2020-01-03T14:43:35Z

As a preparation for adding 64-bit time_t support in the uapi, change the drivers to no longer care about the format of the timestamp field in struct v4l2_buffer. The v4l2_timeval_to_ns() function is no longer needed in the kernel after this, but there is userspace code relying on it to be part of the uapi header.

media: cpia2_usb: fix memory leaks

2019-08-26T13:40:01Z

In submit_urbs(), 'cam->sbuf[i].data' is allocated through kmalloc_array(). However, it is not deallocated if the following allocation for urbs fails. To fix this issue, free 'cam->sbuf[i].data' if usb_alloc_urb() fails. Signed-off-by: Wenwen Wang Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: drivers/media: don't set pix->priv = 0

2019-07-23T12:48:33Z

The priv field of struct v4l2_pix_format shouldn't be set by drivers, it's set by the v4l2 core instead to V4L2_PIX_FMT_PRIV_MAGIC. Drop this from the few media drivers that still do this. Note that the gspca patch is slightly more involved since some of the sub-gspca drivers use the priv field internally.

media: media/usb: don't set description in ENUM_FMT

2019-07-22T18:01:05Z

The V4L2 core sets the description for the driver in order to ensure consistent naming. So drop the strscpy of the description in drivers. Also remove any description strings in driver-internal structures since those are no longer needed. Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab
