Subject: [20/74] net/irda: add missing error path release_sock call

3.2.43-rc1 review patch.  If anyone has any objections, please let me know.

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

From: Kees Cook <keescook@...omium.org>

commit 896ee0eee6261e30c3623be931c3f621428947df upstream.

This makes sure that release_sock is called for all error conditions in
irda_getsockopt.
