From 704b3f4c11e0b1265a41472b6b25dd9e3d205674 Mon Sep 17 00:00:00 2001 From: Markus Elfring Date: Tue, 3 Feb 2015 14:36:35 -0300 Subject: [PATCH] [media] stk-webcam: Delete 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.
