Dear RT folks!

I'm pleased to announce the v6.10.2-rt14 patch set. 

Changes since v6.10.2-rt13:

  - Replace the "seg6_state/ BPF" fixup introduced in v6.10-rc6-rt11
    with a the version, that has been merged upstream.

  - Add another hunk to the i915 to avoid disabling interrupts during
    cursor updates.

Known issues
    None.
