Since compound controls can have non-standard types we need to be able to do type-specific checks etc. In order to make that easy type operations are added. There are four operations: - equal: check if two values are equal - init: initialize a value - log: log the value - validate: validate a new value The v4l2_ctrl struct adds p_new and p_cur unions at the end of the struct. This union provides a standard way of accessing control types through a pointer, which greatly simplifies internal control processing.
