Hi all, I am worried and confused by some Kconfig dependencies in the HID subsystem. There are 11 HID device drivers which are defined in drivers/hid/Kconfig with: tristate "..." if EXPERT default !EXPERT Unless EXPERT is enabled (and that's not the default), these driver entries are hidden and automatically selected. If CONFIG_HID=m, they are selected as modules. If CONFIG_HID=y, they are built into the kernel. So it is impossible to have CONFIG_HID=y and build these device drivers as modules - as device drivers typically are. I would like to understand the reasoning behind this complexity. What is so special about these 11 drivers, that we can't just let the (kernel configuring) user chose if he/she wants them and in what form? Wouldn't "default !EXPERT" and a good old "If unsure, say Y" in the help text be enough? I would be fine with "tristate ... if EXPERT" if I still had the choice between built-in or modular when both are possible. Is there any chance to change the meaning of this construct to that? Also I find it unpleasant that this construct completely hides the option from the user, as if it did not exist, except if other options depend on it. This is inconsistent and makes it difficult for the user to know whether a specific kernel version includes a given driver or not (one has to check .config afterward to know the answer.) Put in short, I don't like the way things are today and would welcome changes in this area.
