	git submodule recurse -a checkout

	Submodule b is not initialized and skipped
	git submodule recurse a checkout
	Please provide an argument: master
	Press y to provide another arg...
	git checkout master
	Already on branch "master"
	Submodule d is not initialized and skipped
	git submodule recurse . checkout
	Please provide an argument: master
	Press y to provide another arg...
	git checkout master
	Already on branch "master"

This command would also come in handy for diffs and other commands.
