MIPS: TXx9: 7segled: add missing put_device call
This is required so that we give up the last reference to the device. Also, add a new tx_7segled_release function which will be called after the put_device to ensure that device is kfree'd. [ralf@linux-mips.org: Reformat to Linux coding style and make tx_7segled_release static.] Signed-off-by: Levente Kurusa <levex@linux.com> Cc: LKML <linux-kernel@vger.kernel.org> Cc: linux-mips@linux-mips.org Patchwork: https://patchwork.linux-mips.org/patch/6260/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
