Subject: [PATCH AUTOSEL 4.14 18/21] net: ep93xx_eth: fix mismatch of request_mem_region in remove
Date: Fri, 22 Nov 2019 14:49:28 -0500 [thread overview]
Message-ID: <20191122194931.24732-18-sashal@kernel.org> (raw)
In-Reply-To: <20191122194931.24732-1-sashal@kernel.org>
From: Chuhong Yuan <hslester96@gmail.com>
[ Upstream commit 3df70afe8d33f4977d0e0891bdcfb639320b5257 ]
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.
