Subject: [PATCH] io_uring: fix uninitialized error code in io_eventfd_register()
Date: Tue, 8 Feb 2022 10:41:03 +0300	[thread overview]
Message-ID: <20220208074103.GA26588@kili> (raw)

The "ret" variable isn't initialized.  We should just return 0.

Fixes: b77e315a9644 ("io_uring: avoid ring quiesce while registering/unregistering eventfd")
