    kbuild: Warn on selecting symbols with unmet direct dependencies · 246cf9c2
    Catalin Marinas authored
    The "select" statement in Kconfig files allows the enabling of options
    even if they have unmet direct dependencies (i.e. "depends on" expands
    to "no"). Currently, the "depends on" clauses are used in calculating
    the visibility but they do not affect the reverse dependencies in any
    way.
    
    The patch introduces additional tracking of the "depends on" statements
    and prints a warning on selecting an option if its direct dependencies
    are not met.
