From f18379a30271c0289c2d0e1074e1ed633bfd708c Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Sun, 1 May 2022 17:40:19 +0900 Subject: modpost: split new_symbol() to symbol allocation and hash table addition new_symbol() does two things; allocate a new symbol and register it to the hash table. Using a separate function for each is easier to understand. Replace new_symbol() with hash_add_symbol(). Remove the second parameter of alloc_symbol().
