target/linux/generic/hack-5.10/205-kconfig-exit.patch

   1 From: David Bauer <mail@david-bauer.net>
   2 Subject: Kconfig: exit on unset symbol
   3
   4 When a target configuration has unset Kconfig symbols, the build will
   5 fail when OpenWrt is compiled with V=s and stdin is connected to a tty.
   6
   7 In case OpenWrt is compiled without either of these preconditions, the
   8 build will succeed with the symbols in question being unset.
   9
  10 Modify the kernel configuration in a way it fails on unset symbols
  11 regardless of the aforementioned preconditions.
