Running the presubmit.sh script will apply our rules to every file in the repo. Exclude gbm.h from the formatting requirements since this file was taken from other open-source projects, and diffing will be easier without our formatting rules. In addition, special case drivers where the order of includes matters. BUG=none TEST=Verified the following commands succeed: emerge-cyan minigbm/arc-cros-gralloc emerge-oak minigbm/arc-cros-gralloc emerge-veyron_minnie-cheets minigbm/arc-cros-gralloc emerge-peach_pi minigbm emerge-nyan_big minigbm emerge-jadeite minigbm Change-Id: I6ce93fb1930da254d13d5017766c17341870ccc9 Reviewed-on: https://chromium-review.googlesource.com/447319 Commit-Ready: Gurchetan Singh <gurchetansingh@chromium.org> Tested-by: Gurchetan Singh <gurchetansingh@chromium.org> Reviewed-by: Gurchetan Singh <gurchetansingh@chromium.org>
