From e3b09e4bf6455caccc7ef215256e4f0065fbca7d Mon Sep 17 00:00:00 2001 From: Jesper Juhl Date: Mon, 16 Jan 2012 21:28:37 +0100 Subject: [PATCH] staging, vt6656/wpactl.c: Fix mem leak in wpa_ioctl() If we hit the default case in the switch statement in wpa_ioctl() we'll leak the memory allocated to 'param' when the variable goes out of scope without having been assigned to anything. This patch fixes the leak by kfree()'ing the memory before we return from the function.
