QGIS is an open source project and we appreciate contributions very much.

Before making a pull request, please make sure your code is properly formatted by running the prepare commit script before issuing git commit.

./scripts/prepare-commit.sh

This can be automated by setting up the pre-commit hook properly.

ln -s scripts/prepare-commit.sh .git/hooks/pre-commit

This is a volunteer project, so sometimes it may take a little while to merge your pull request.

There is a guide with hints for getting your pull requests merged in the developers guide.
