Each patch is independent of the others, but I've grouped\nthem in this series because they're very similar, so it should ease the review.\n\nThe patches here are based on these patches that added the same functionality\nfor the ipu3 pipeline handler: 5a9d19210fad (\"libcamera: pipeline: ipu3: Try\nqueuing pending requests if a buffer is available\") and 89dae5844964\n(\"libcamera: pipeline: ipu3: Store requests in the case a buffer shortage\").\n\nWith these patches applied, the lc-compliance test from [1] passes in all three\npipeline handlers.\n\n[1] https://lists.libcamera.org/pipermail/libcamera-devel/2021-July/022356.html\n\nPrevious standalone versions of the patches: uvcvideo [2] and rkisp1 [3]\n\n[2] https://lists.libcamera.org/pipermail/libcamera-devel/2021-July/022029.html\n[3] https://lists.libcamera.org/pipermail/libcamera-devel/2021-July/022135.html\n\nNícolas F.
