Subject: [PATCH 18/27] modpost: make sym_add_exported() a void function
Date: Mon, 25 Apr 2022 04:08:02 +0900 [thread overview]
Message-ID: <20220424190811.1678416-19-masahiroy@kernel.org> (raw)
In-Reply-To: <20220424190811.1678416-1-masahiroy@kernel.org>
Currently, sym_add_exported() returns the pointer to the added symbol
just for doing:
s->is_static = false;
in the read_dump() function.
I noticed it was unneeded because sym_add_exported() can know the proper
default for the 'is_static' member by checking mod->from_dump.
This makes the code slightly simpler.
