From: Lad, Prabhakar Date: Fri, 16 May 2014 13:33:45 +0000 (-0300) Subject: [media] media: davinic: vpif_capture: drop started member from struct common_obj X-Git-Tag: firefly_0821_release~176^2~3573^2~76 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=c66238f363b3c39c6aaa85d9c938a3d17eb9a352;p=firefly-linux-kernel-4.4.55.git [media] media: davinic: vpif_capture: drop started member from struct common_obj the started member was indicating whether streaming was started or not, this can be determined by vb2 offering, this patch replaces the started member from struct common_obj with appropriate vb2 calls.
