Hello all,

I'm building an off-tree kernel-dependent package (iscsitarget),
which results a set of kernel modules. This is a cross-platform build,
with a toolchain installed on an old RH7.3 host (host GCC v2.96)

Unfortunately, build fails with the following error:
->

The origin of the error is obvious - C99 declaration in match().

The patch is trivial:
