This is required by some software, e.g. bluez/gnome to set some ACLs on
/dev/rfkill (see #904). While probably nobody will notice on the
downstream kernels (as we don't have any proper software there anyways)
it's definitely needed on mainline-ish kernels. Surprisingly only one
kernel has broken by enabling this option (linux-sony-tulip) which I've
patched up.
linux-postmarketos-qcom-sdm660 did not break by enabling this option,
but required linux4.17-gcc10-extern_YYLOC_global_declaration.patch to
build again, so this was fixed too.
