Subject: [PATCH] yaffs2: fix memory leak when /proc/yaffs is read
commit 27f18203551940abf35826a66978daf1b8124c6b from
git://www.aleph1.co.uk/yaffs2
Thanks to Jisheng Zhang <Jisheng.Zhang@synaptics.com> for supplying this patch
There is a kernel memory leak observed when the proc file /proc/yaffs
is read. This reason is that in yaffs_proc_open, single_open is called
and the respective release function is not called during release.
Fix with correct release function - single_release().
