Subject: [ 28/29] can: gw: use kmem_cache_free() instead of kfree()

3.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Wei Yongjun <yongjun_wei@...ndmicro.com.cn>

commit 3480a2125923e4b7a56d79efc76743089bf273fc upstream.

Memory allocated by kmem_cache_alloc() should be freed using
kmem_cache_free(), not kfree().
