[PATCH 2/2] staging, vt6656/wpactl.c: Fix mem leak in wpa_ioctl()

From: Jesper Juhl
Date: Mon Jan 16 2012 - 15:28:41 EST


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.
