Subject: [PATCH] ethernet: sun: Free the coherent when failing in probing
Date: Sat, 5 Mar 2022 14:55:04 +0000 [thread overview]
Message-ID: <1646492104-23040-1-git-send-email-zheyuma97@gmail.com> (raw)
When the driver fails to register net device, it should free the DMA
region first, and then do other cleanup.
