Subject: drm/sun4i: backend: remove redundant dev_err call in sun4i_backend_bind()
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=9a8aa939ba33998f4c70c082dbd4d27a5ddcaaf6;p=openwrt%2Fstaging%2Fblogic.git

drm/sun4i: backend: remove redundant dev_err call in sun4i_backend_bind()

There is a error message within devm_ioremap_resource
already, so remove the dev_err call to avoid redundant
error message.
