Use kvzalloc() instead of kzalloc() to allocate memory to cache the content of a firmware control. Most firmware controls are only small, typically a few bytes. But on some firmware there can be much larger controls for coefficient or model data. The overhead of kvzalloc() is negligible because most control allocs can be satisfied by the normal kmalloc() that kvzalloc() will try first.
