Subject: [PATCH] module: potential uninitialized return in
module_kallsyms_on_each_symbol()
Smatch complains that:
kernel/module.c:4472 module_kallsyms_on_each_symbol()
error: uninitialized symbol 'ret'.
This warning looks like it could be correct if the &modules list is
empty.
Fixes: 013c1667cf78 ("kallsyms: refactor {,module_}kallsyms_on_each_symbol")
