media: v4l: Memset argument to 0 before calling get_mbus_config pad op

2025-06-04T12:37:04+00:00

[ Upstream commit 91d6a99acfa5ce9f95ede775074b80f7193bd717 ] Memset the config argument to get_mbus_config V4L2 sub-device pad operation to zero before calling the operation. This ensures the callers don't need to bother with it nor the implementations need to set all fields that may not be relevant to them.

media: subdev: disallow ioctl for saa6588/davinci

2021-07-19T07:45:02+00:00

commit 0a7790be182d32b9b332a37cb4206e24fe94b728 upstream. The saa6588_ioctl() function expects to get called from other kernel functions with a 'saa6588_command' pointer, but I found nothing stops it from getting called from user space instead, which seems rather dangerous. The same thing happens in the davinci vpbe driver with its VENC_GET_FLD command. As a quick fix, add a separate .command() callback pointer for this driver and change the two callers over to that. This change can easily get backported to stable kernels if necessary, but since there are only two drivers, we may want to eventually replace this with a set of more specialized callbacks in the long run.

2020-08-18T13:45:23+00:00

With all sensor and platform drivers now converted to use the new get_mbus_config and set_mbus_config pad operations, remove the deprecated video operations g_mbus_config and s_mbus_config. Signed-off-by: Jacopo Mondi Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: v4l2-subdev: Introduce [get|set]_mbus_config pad ops

2020-08-18T13:34:22+00:00

Introduce two new pad operations to allow retrieving and configuring the media bus parameters on a subdevice pad. The newly introduced operations aims to replace the s/g_mbus_config video operations, which have been on their way for deprecation since a long time.

2020-05-18T09:12:52+00:00

Add a convenience function that can be used as the .get_fwnode_pad operation for subdevices that map port numbers and pad indexes 1:1. The function verifies the endpoint is owned by the subdevice, and if so returns the endpoint port number.
