4.3-stable review patch. If anyone has any objections, please let me know. ------------------ From: Hans Verkuil <hans.verkuil@xxxxxxxxx> commit 35204e2e84f2dae72012f8ca319659c12f428430 upstream. Array controls weren't skipped when only V4L2_CTRL_FLAG_NEXT_CTRL was provided (so no V4L2_CTRL_FLAG_NEXT_COMPOUND was set). This is wrong since arrays are also considered compound controls (i.e. with more than one value), and applications that do not know about arrays will not be able to handle such controls. Fix the test to include arrays.
