[ Upstream commit a829dd5b3840fd9a24608ed73eb21ba239ae5334 ] This patch fixes various trivial coding-style issues in usx2y code, such as: * the assginments in if condition * comparison order with constants * NULL / zero checks * unsigned -> unsigned int * addition of braces in control blocks * debug print with function names * move local variables in block into function head * reduction of too nested indentations No functional changes.
