[beagleboard] Using PRU to control PWM peripheral on kernel 4.1 - DTO problem?

I wrote pasm code that has the PRU set up a 10%-duty-cycle 33kHz square wave using PWM on the ehrpwm1B peripheral (which maps to P8_34 in mode 2). It worked on the 3.18 kernel but doesn't work on 4.1.12. When my C code tries to start the PRU code, prussdrv_open returns -1 (bad). I think the pro
