Re: [PATCH 2/3] video: fbdev: ssd1307fb: Print the PWM's label instead of its number

struct pwm_device::pwm is a write-only variable in the pwm core and used
nowhere apart from this and another dev_dbg. So it isn't useful to
identify the used PWM. Emit the PWM's label instead in the debug
message.

applied.

Thanks!
