Subject: [PATCH AUTOSEL 4.14 3/6] rocker: fix incorrect error handling in dma_rings_init
Date: Tue, 23 Jun 2020 13:36:46 -0400 [thread overview]
Message-ID: <20200623173649.1356142-3-sashal@kernel.org> (raw)
In-Reply-To: <20200623173649.1356142-1-sashal@kernel.org>
From: Aditya Pakki <pakki001@umn.edu>
[ Upstream commit 58d0c864e1a759a15c9df78f50ea5a5c32b3989e ]
In rocker_dma_rings_init, the goto blocks in case of errors
caused by the functions rocker_dma_cmd_ring_waits_alloc() and
rocker_dma_ring_create() are incorrect. The patch fixes the
order consistent with cleanup in rocker_dma_rings_fini().
