From d0fd64c1de437bdf91c32d4f84a53fa4b2150348 Mon Sep 17 00:00:00 2001 From: Pavel Shved Date: Fri, 17 Jun 2011 06:25:10 +0000 Subject: [PATCH] farsync: add module_put to error path in fst_open() The fst_open() function, after a successful try_module_get() may return an error code if hdlc_open() returns it. However, it does not put the module on this error path. This patch adds the necessary module_put() call. Found by Linux Driver Verification project (linuxtesting.org).
