From c8edbfb2cc44ad78a8cfbdd6a0cd1af863e199fd Mon Sep 17 00:00:00 2001 From: =?utf8?q?Philippe=20Mathieu-Daud=C3=A9?= Date: Fri, 21 Aug 2020 21:53:50 +0200 Subject: [PATCH] block/nvme: Use common error path in nvme_add_io_queue() MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Rearrange nvme_add_io_queue() by using a common error path. This will be proven useful in few commits where we add IRQ notification to the IO queues.
