From 8a102fd6c99a26a0aa74e3d4bed4092b3c791361 Mon Sep 17 00:00:00 2001 From: Peter Senna Tschudin Date: Fri, 15 Jan 2016 18:41:32 +0100 Subject: [PATCH] usb-misc: sisusbvga: Remove null test before calls to kfree() This patch removes null test before calls to kfree() as kfree() can handle null pointers safely.
