From de69113ec1896443c732e8b812e8005fb44eeeeb Mon Sep 17 00:00:00 2001 From: Axel Lin Date: Thu, 4 Aug 2011 07:58:07 +0800 Subject: TPM: tpm_nsc: Fix a double free of pdev in cleanup_nsc platform_device_unregister() will release all resources and remove it from the subsystem, then drop reference count by calling platform_device_put(). We should not call kfree(pdev) after platform_device_unregister(pdev).
