This is a note to let you know that I've just added the patch titled

 spi: Fix controller unregister order

to the 4.4-stable tree which can be found at:

[...]

...

--- a/drivers/spi/spi.c +++ b/drivers/spi/spi.c @@ -1922,11 +1922,12 @@ void spi_unregister_master(struct spi_master *master) dev_err(&master->dev, "queue remove failed\n"); }

• device_for_each_child(&master->dev, NULL, __unregister);

This is a wrong patch. We should move this line before spi_destroy_queue, but we didn't. 4.9 stable exists this problem too.

Hi Sasha, Hi Greg,

below please find a patch for the 4.9-stable tree to fix the backporting issue reported above.

Now applied, thanks.
