Re: [V9fs-developer] [Patch] Dead code in fs/9p/vfs_inode.c

coverity (id #971) found some dead code. In all error
cases ret is NULL, so we can remove the if statement.

What about when someone changes the code and does have ret != NULL here?
This seems like reasonable defensive programming to me.

Is the official LK policy that we can't have code that trips coverity
checks like this?
