Usual formatting convention here seems to be to surround the expression
with parentheses.  Same thing again later in your patch.

Parens again to move function args to the right.  You probably should be
honouring info->keep_memory here.  ie. pass it in to the read_relocs
func, and free the relocs once you're done if keep_memory is false.

(*reloc_emitter) for K&R compatibility, and same thing a little later.

Other than that, the patch looks OK to me.
