From: Sasha Finkelstein <fnkl.kernel@xxxxxxxxx> commit b76abe4648c1acc791a207e7c08d1719eb9f4ea8 upstream. This patch fixes an incorrect loop exit condition in code that replaces '/' symbols in the board name. There might also be a memory corruption issue here, but it is unlikely to be a real problem.
