Subject: [PATCH] sched/deadline: remove unused dl_bandwidth
Date: Wed, 24 May 2023 18:25:14 +0800	[thread overview]
Message-ID: <20230524102514.407486-1-linmiaohe@huawei.com> (raw)

The default deadline bandwidth control structure has been removed since
commit eb77cf1c151c ("sched/deadline: Remove unused def_dl_bandwidth")
leading to unused init_dl_bandwidth() and struct dl_bandwidth. Remove
them to clean up the code.
