media: vivid: use prandom

2025-10-30T17:35:26Z

This is part of a prandom cleanup, which removes next_pseudo_random32 and replaces it with the standard PRNG. Signed-off-by: Markus Theil Reviewed-by: Krzysztof Karas Signed-off-by: Jason A. Donenfeld

media: vivid: use vmalloc_array and vcalloc to simplify code

2025-10-14T13:07:36Z

Remove array_size() calls and replace vmalloc(array_size()) with vmalloc_array() and vzalloc(array_size()) with vcalloc() to simplify the code. Signed-off-by: Qianfeng Rong Signed-off-by: Hans Verkuil

media: vivid: fix disappearing messages

2025-09-09T14:12:56Z

The vivid driver supports the message, but if the Vendor ID of the received message didn't match the Vendor ID of the CEC Adapter, then it ignores it (good) and returns 0 (bad). It should return -ENOMSG to indicate that other followers should be asked to handle it. Return code 0 means that the driver handled it, which is wrong in this case. As a result, userspace followers never get the chance to process such a message. Refactor the code a bit to have the function return -ENOMSG at the end, drop the default case, and ensure that the message handlers return 0. That way 0 is only returned if the message is actually handled in the vivid_received() function.

media: test-drivers: Rename second ioctl handlers argument to 'void *priv'

2025-08-13T06:33:58Z

The second argument to the ioctl handlers is not a file handle any more. Rename it from 'void *fh' to 'void *priv', to avoid misconceptions. This is particularly important in test drivers as they are meant to be used as reference implementations. Signed-off-by: Laurent Pinchart Signed-off-by: Hans Verkuil

media: Replace file->private_data access with file_to_v4l2_fh()

2025-08-13T06:33:25Z

Accessing file->private_data manually to retrieve the v4l2_fh pointer is error-prone, as the field is a void * and will happily cast implicitly to any pointer type. Replace all remaining locations that read the v4l2_fh pointer directly from file->private_data with usage of the file_to_v4l2_fh() function. The change was generated manually. 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.

media: vivid: fix wrong pixel_array control size

2025-07-08T07:02:38Z

The pixel_array control size was calculated incorrectly: the dimensions were swapped (dims[0] should be the height), and the values should be the width or height divided by PIXEL_ARRAY_DIV and rounded up. So don't use roundup, but use DIV_ROUND_UP instead. This bug is harmless in the sense that nothing will break, except that it consumes way too much memory for this control.
