MIPS: TXx9: Add missing put_device call
This is required so that we give up the last reference to the device. Also, rework error path so that it is easier to read. [ralf@linux-mips.org: Reformat to Linux coding style and make txx9_device_release static; folded in build fix by Levente for the original patch.] Signed-off-by: Levente Kurusa <levex@linux.com> Cc: LKML <linux-kernel@vger.kernel.org> Cc: Aaro Koskinen <aaro.koskinen@iki.fi> Cc: Markos Chandras <markos.chandras@imgtec.com> Cc: Steven J.
