kconfig: fix segfault when detecting recursive dependency
Following sample Kconfig generated a segfault: config FOO bool select PERF_EVENTS if HAVE_HW_BREAKPOINT config PERF_EVENTS bool config HAVE_HW_BREAKPOINT bool depends on PERF_EVENTS Fix by reverting back to a valid property if there was no property on the stack of symbols. The above pattern were seen in sh Kconfig. A fix for the Kconfig file has been sent to the sh folks. Signed-off-by: NSam Ravnborg <sam@ravnborg.org> Signed-off-by: NMichal Marek <mmarek@suse.cz>
