Series v4l2-tracer: track changes from syncing with kernel | expand

Commit Message

Deborah Brouwer Nov. 27, 2023, 8:09 p.m. UTC 
After v4l-utils is synced with the latest kernel headers, generate and
apply patches for the changes that need to be made to the v4l2-tracer.
This makes it easier to see how the kernel headers are changing the
v4l2-tracer and also to revert those changes if necessary.
