The second patch was first sent alone, then it was sent again as part of the patchset "media: vimc: use configfs in order to configure devices topologies" It fixes a crashing bug when the pipeline does not start with a source entity. Fixes from v3: - set the error value to -EINVAL when the vimc entity pointer is not found in vimc_streamer_pipeline_init - have more precise error messages in vimc_streamer_pipeline_init Dafna Hirschfeld (2): media: vimc: move the dev field of each entity to vimc_ent_dev media: vimc: upon streaming, check that the pipeline starts with a source entity drivers/media/platform/vimc/vimc-capture.c | 7 +++-- drivers/media/platform/vimc/vimc-common.c | 10 +++++++ drivers/media/platform/vimc/vimc-common.h | 7 +++++ drivers/media/platform/vimc/vimc-debayer.c | 15 +++++------ drivers/media/platform/vimc/vimc-scaler.c | 11 ++++---- drivers/media/platform/vimc/vimc-sensor.c | 5 ++-- drivers/media/platform/vimc/vimc-streamer.c | 29 ++++++++++++++------- 7 files changed, 53 insertions(+), 31 deletions(-) -- 2.20.1
