The vivid driver uses a complex logic to save one kalloc/kfree allocation. That non-trivial way of allocating data causes smatch to warn: drivers/media/platform/vivid/vivid-core.c:869 vivid_create_instance() warn: potentially one past the end of array 'dev->query_dv_timings_qmenu[dev->query_dv_timings_size]' drivers/media/platform/vivid/vivid-core.c:869 vivid_create_instance() warn: potentially one past the end of array 'dev->query_dv_timings_qmenu[dev->query_dv_timings_size]' I also needed to read the code several times in order to understand what it was desired there. It turns that the logic was right, although confusing to read. As it is doing allocations on a non-standard way, let's add some documentation while shutting up the false positive.
