The first patch in this patchset moves the dev field of each entity struct to the common sturct vimc_ent_device, this is used by the first and the second patch to have access to 'dev' in the streamer and replace pr_err with dev_err. 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" I send it now again since it is not directly related to that patchset and it fixes a crashing bug. It has the following fixes due to Shuah Khan's comments: - add the panic message to the commit message - move the function vimc_is_source to the vimc-common.c file - replace pr_err with dev_err 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, 51 insertions(+), 33 deletions(-) -- 2.20.1
