Kconfig makes a distinction between dependencies (defined by "depends on" expressions and enclosing "if" blocks) and visibility (which includes all dependencies, but also includes inline "if" expressions of individual properties as well as, for prompts, "visible if" expressions of enclosing menus). Before commit bcdedcc1 ("menuconfig: print more info for symbol without prompts"), the "Depends on" lines of a symbol's help text indicated the visibility of the prompt property they appeared under. After bcdedcc1, there was always only a single "Depends on" line, which indicated the visibility of the first P_SYMBOL property of the symbol. Since P_SYMBOLs never have inline if expressions, this was in effect the same as the dependencies of the menu item that the P_SYMBOL was attached to. Neither of these situations accurately conveyed the dependencies of a symbol--the first because it was actually the visibility, and the second because it only showed the dependencies from a single definition. With this series, we are back to printing separate dependencies for each definition, but we print the actual dependencies (rather than the visibility) in the "Depends on" line. However, it can still be useful to know the visibility of a prompt, so this patch adds a "Visible if" line that shows the visibility only if the visibility is different from the dependencies (which it isn't for most prompts in Linux).
