I had following compilation error: drivers/media/video/isp/ispvideo.c: In function 'isp_video_streamon': drivers/media/video/isp/ispvideo.c:780: error: 'const struct isp_video_operations' has no member named 'stream_off' drivers/media/video/isp/ispvideo.c:781: error: 'const struct isp_video_operations' has no member named 'stream_off' make[4]: *** [drivers/media/video/isp/ispvideo.o] Error 1 make[3]: *** [drivers/media/video/isp] Error 2 make[3]: *** Waiting for unfinished jobs.... make[2]: *** [drivers/media/video] Error 2 make[1]: *** [drivers/media] Error 2 make: *** [drivers] Error 2 Which I solved with the attached patch. You might want to squash it with your patch "omap3isp: video: Remove the init, cleanup and stream_off operations" I'll continue trying to bring up my sensor, and let you know if I have other query. Thanks for your time! Regards, Sergio > > -- > Regards, > > Laurent Pinchart
