Each patch is independent of the others, but I've grouped them in this series because they're very similar, so it should ease the review. The patches here are based on these patches that added the same functionality for the ipu3 pipeline handler: 5a9d19210fad ("libcamera: pipeline: ipu3: Try queuing pending requests if a buffer is available") and 89dae5844964 ("libcamera: pipeline: ipu3: Store requests in the case a buffer shortage"). With these patches applied, the lc-compliance test from [1] passes in all three pipeline handlers.
