[GIT PULL] rtla: Couple of fixes for 6.17

[GIT PULL] rtla: Couple of fixes for 6.17

[Steven Rostedt]

Linus,

Two fixes for rtla in v6.17:

- Fix a buffer overflow in actions_parse()

  The "trigger_c" variable did not account for the nul byte when
  determining its size.

- Fix a compare that had the values reversed

  actions_destroy() is to reallocate when len is greater than the current size,
  but the compare was testing if size is greater than the new length.
