Subject: [PATCH] object-name: declare pointer type of extend_abbrev_len()'s 2nd parameter

From: René Scharfe <[email-masked]>
Date: Thu, 4 Sep 2025 19:58:25 +0200

Expose the expected type of the second parameter of extend_abbrev_len()
instead of casting a void pointer internally.  Just a single caller
passes in a void pointer, the rest pass the correct type.  Let the
compiler help keeping it that way.
