mrf24j40: Use level-triggered interrupts
The mrf24j40 generates level interrupts. There are rare cases where it appears that the interrupt line never gets de-asserted between interrupts, causing interrupts to be lost, and causing a hung device from the driver's perspective. Switching the driver to interpret these interrupts as level-triggered fixes this issue. Signed-off-by: Alan Ott <alan@signal11.us> Signed-off-by: David S. Miller <davem@davemloft.net>
