Subject: [PATCH] sound/core/seq: remove dead code
Date: Sun, 1 Nov 2020 23:11:54 -0800 [thread overview]
Message-ID: <20201102071154.23563-1-yuhaobehappy@gmail.com> (raw)
The function snd_seq_queue_client_termination() is only called from
function seq_free_client1(). The seq_free_client1() calls function
snd_seq_queue_client_leave(), which deletes all objects whose owner
equals to client->number in global array queue_list, before the function
snd_seq_queue_client_termination(), which checks whether there are
any objects in global array queue_list whose owner equals to
client->number, with the same argument client->number. So
the checking code in function snd_seq_queue_client_termination() is
dead code. Remove those dead code.
