Replace this ad-hoc\nmechanism by passing the corresponding data back from the IPA to the\npipeline handler through the configure() response. This allows\nsynchronous handling of the response on the pipeline handler side.\n\nSigned-off-by: Laurent Pinchart \n---\n include/libcamera/ipa/raspberrypi.h | 3 +-\n
