Subject: [PATCH] ALSA: seq: add error check in snd_seq_system_client_init()
Git-commit: c4f1957e14444e444b35418e85069b7ab65465a5
Patch-mainline: v4.20-rc1
References: bsc#1121278
Static checkers complain that snd_seq_create_kernel_client() can return
-EBUSY here so we need to have some error handling.
