Subject: [PATCH AUTOSEL 5.10 09/12] ethernet: sun: Free the coherent when failing in probing
Date: Wed, 16 Mar 2022 10:16:33 -0400	[thread overview]
Message-ID: <20220316141636.248324-9-sashal@kernel.org> (raw)
In-Reply-To: <20220316141636.248324-1-sashal@kernel.org>

From: Zheyu Ma <zheyuma97@gmail.com>

[ Upstream commit bb77bd31c281f70ec77c9c4f584950a779e05cf8 ]

When the driver fails to register net device, it should free the DMA
region first, and then do other cleanup.
