Subject: [PATCH] net: ep93xx_eth: fix mismatch of request_mem_region in remove
Date: Thu, 14 Nov 2019 23:43:24 +0800 [thread overview]
Message-ID: <20191114154324.31990-1-hslester96@gmail.com> (raw)
The driver calls release_resource in remove to match request_mem_region
in probe, which is incorrect.
Fix it by using the right one, release_mem_region.
