Do these devices need this additional "protection"? Do they have the problem that these macros were written for? Same for the other patches you just submitted here, I think you need to somehow "prove" that these changes are necessary, checkpatch isn't able to determine this all the time. thanks, greg k-h _______________________________________________ amd-gfx mailing list amd-gfx@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/amd-gfx
