What exactly is unclear about the message? The write fails (for
whatever reason). I should probably print out the return value as
More interestingly is the register address. 0x30 is the current PWM
duty-cycle. It only gets written during driver initialization or if
userland does manual PWM control.

What apps are you running that touch the driver? Are you doing manual
PWM control?
