From a514f9f35dc1e0ae0bf3284594b751943e56ea70 Mon Sep 17 00:00:00 2001 From: Markus Elfring Date: Tue, 25 Nov 2014 22:33:45 +0100 Subject: [PATCH] net: Hyper-V: Deletion of an unnecessary check before the function call "vfree" The vfree() function performs also input parameter validation. Thus the test around the call is not needed. This issue was detected by using the Coccinelle software. Signed-off-by: Markus Elfring Signed-off-by: Haiyang Zhang Signed-off-by: David S.
