From 5775f00e1206fd425609c26ee9a3620149e567ac Mon Sep 17 00:00:00 2001 From: Mario Six Date: Mon, 15 Jan 2018 11:08:22 +0100 Subject: [PATCH] net: tsec: Fix memory leak in error path tsec_initialize allocates a private driver structure using malloc. Should the memory allocation of this private structure fail, the function execution is aborted with a return 0, but the previously allocated device structure is never freed, hence leaked. Free the device structure in the error case.
