Hi Sam,

Until we get the fix submitted to stable, you'll unfortunately have
to use kernels older than 4.4 or use 4.6 when the fix is applied to
mainline. There's no viable work-around without changing the driver.

If you want to apply a kernel patch to your own tree in the meantime,
a possible work-around patch is provided here:
