Hi Marc,

With your patch applied, the warning is gone, thanks.

The touchscreen is registered:

[    8.207461] input: mxs-lradc-ts as
/devices/soc0/80000000.apb/80040000.apbx/80050000.lradc/mxs-lradc-ts/input/input0

but when I run  "cat /dev/input/event0" and touch the screen, no irq
event is generated.

Looking at cat /proc/interrupts shows that no mxs-lradc-touchscreen
irq happened:

216:          0         -  10 Edge      mxs-lradc-touchscreen

Thanks
