That's annoying, I thought I did build test the final changes.
However, there's a mistake in the Makefile meaning that it wasn't
building with no warning/error messages - it actually wasn't building
at all!  Sorry about that Thierry.

I guess if you can build the driver, you've already fixed that?


After that change, I can see that you're absolutely correct:

  CC      drivers/pwm/pwm-sti.o
../drivers/pwm/pwm-sti.c: In function ‘sti_pwm_config’:
../drivers/pwm/pwm-sti.c:202:3: warning:
  format ‘%lu’ expects argument of type ‘long unsigned int’, but
  argument 5 has type ‘int’ [-Wformat=]
     dev_dbg(dev, "prescale:%u, period:%lu, duty:%i, pwmvalx:%u\n",
     ^
../drivers/pwm/pwm-sti.c: In function ‘sti_pwm_probe’:
../drivers/pwm/pwm-sti.c:352:31: error: ‘np’ undeclared 
  pc->clk = of_clk_get_by_name(np, "pwm");
                               ^
Sorry for the fuss.

Yes, it should be all taken care of in the PWM for-next branch.
