Series media: vimc: upon streaming, check that the pipeline starts with a source entity | expand

Commit Message

Dafna Hirschfeld Oct. 9, 2019, 3:53 p.m. UTC
Since the 'struct device *dev' field exists in each of the
entity structs, it can be moved to the common struct vimc_ent_devevice.
It is then used to replace 'pr_err' with 'dev_err' in the streamer
code.
