media: Wrap file->private_data access with a helper function

2025-08-13T06:33:23Z

Accessing file->private_data manually to retrieve the v4l2_fh pointer is error-prone, as the field is a void * and will happily convert implicitly to any pointer type. To avoid direct access to file->private_data, introduce a new inline function that retrieves the v4l2_fh pointer, and use it to replace common access patterns through the kernel. Changes to drivers have been generated with the following coccinelle semantic patch: @@ struct file *filp; identifier fh; @@ - struct v4l2_fh *fh = filp->private_data; + struct v4l2_fh *fh = file_to_v4l2_fh(filp); Manual changes have been applied to Documentation/ to update the usage patterns, and to include/media/v4l2-fh.h to add the new function. While at it, fix a typo in the title of v4l2-fh.rst: the file describes the "file handles" API, not "file handlers". No functional change is intended, this only paves the way to remove direct accesses to file->private_data and make V4L2 drivers safer. Other accesses to the field will be addressed separately.

This loop was recently converted to use for_each_of_graph_port() which automatically does __cleanup__ on the "port" iterator variable. Delete the calls to of_node_put(port) to avoid a double put bug.

media: platform: drop vb2_ops_wait_prepare/finish

2024-10-28T08:20:07Z

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 Reviewed-by: Neil Armstrong # for meson-ge2d Acked-by: Andrzej Pietrasiewicz

media: Switch back to struct platform_driver::remove()

2024-10-12T14:28:25Z

After commit 0edb555a65d1 ("platform: Make platform_driver::remove() return void") .remove() is (again) the right callback to implement for platform drivers. Convert all platform drivers below drivers/media to use .remove(), with the eventual goal to drop struct platform_driver::remove_new(). As .remove() and .remove_new() have the same prototypes, conversion is done by just changing the structure member name in the driver initializer.
