From 4b0a22bd0d496c562c34592c23f445540ca88f6b Mon Sep 17 00:00:00 2001 From: Dinghao Liu Date: Mon, 24 Aug 2020 13:58:31 +0800 Subject: net: systemport: Fix memleak in bcm_sysport_probe [ Upstream commit 7ef1fc57301f3cef7201497aa27e89ccb91737fe ] When devm_kcalloc() fails, dev should be freed just like what we've done in the subsequent error paths.
