Created attachment 175823 [details] fix cam.ko build outside of KERNBUILDDIR cam.ko does not build outside of KERNBUILDDIR due to missing "opt_ddb.h" file. Attached patch fixes this.
The issue was fixed by commits on ^/head that weren't MFCed to stable branches. I fixed the issue in ^/stable/11 by r312356 and in ^/stable/10 by r312357 (r312357 required MFCing r299864 as well). Thank you for the report!
