In the current code, gk20a.h includes io.h which gets directly included in a lot of other files. io.h contains methods which uses a struct gk20a as a parameter leading to a circular dependency between io.h and gk20a.h. This can be mitigated by removing io.h from gk20a.h as part of larger effort to moving gk20a.h to nvgpu/gk20a.h JIRA NVGPU-597 Change-Id: I93e504fa9371b88152737b342a75580c65e8f712 Signed-off-by: Debarshi Dutta <ddutta@nvidia.com> Reviewed-on: https://git-master.nvidia.com/r/1787316 Reviewed-by: mobile promotions <svcmobile_promotions@nvidia.com> Tested-by: mobile promotions <svcmobile_promotions@nvidia.com>
