Subject: net: ethernet: ti: ale: use devm_kzalloc in cpsw_ale_create()
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=1971ab587bb087905ff94a079184b0608d0075ff;p=openwrt%2Fstaging%2Fblogic.git

net: ethernet: ti: ale: use devm_kzalloc in cpsw_ale_create()

Use cpsw_ale_create in cpsw_ale_create(). This also makes
cpsw_ale_destroy() function nop, so remove it.
