Subject: drm/fsl-dcu: remove unneeded 'ret' assignment
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=5d2883d51d60ce34a773d4a07b468216109d9030;p=openwrt%2Fstaging%2Fblogic.git

drm/fsl-dcu: remove unneeded 'ret' assignment

When devm_kzalloc() fails there is no need to assign an error code
to the 'ret' variable as it will not be used after jumping to the
'err_node_put' label, so just remove the assignment.
