This change is based on Laurent's feedback on the earlier series, and\nI am happy to take suggestions on how this could be improved.\n\nThanks,\nNaush\n\nNaushir Patuck (3):\n ipa: raspberrypi: Embed the metadata parser in the sensor CamHelper\n classes\n ipa: raspberrypi: Fix possible buffer overrun in metadata parsing\n ipa: raspberrypi: Generalise the SMIA metadata parser\n\n src/ipa/raspberrypi/cam_helper.cpp | 36 ++++---\n src/ipa/raspberrypi/cam_helper.hpp | 2 +\n src/ipa/raspberrypi/cam_helper_imx219.cpp | 118 +++++---------------\n src/ipa/raspberrypi/cam_helper_imx477.cpp | 124 +++++-----------------\n src/ipa/raspberrypi/md_parser.hpp | 42 +++++---\n src/ipa/raspberrypi/md_parser_smia.cpp | 70 +++++++++---\n 6 files changed, 152 insertions(+), 240 deletions(-)"}
