syscon_regmap_lookup_by_phandle() returns ERR_PTR on error.
Thus don't use null test against state->regmap.

Olof,
I think the way Javier did it is fine, the 'major' of the ioctl is

It was necessary to decouple code handling writing to sysfs from the one
responsible for setting PWM of the fan.
Due to that, new __set_pwm() method was extracted, which is responsible for
only setting new PWM duty cycle.

Add pwm-fan node to the Odroid-U3 board file to enable PWM control of the

Presented patches add support for Odroid's U3 optional CPU FAN, which uses PWM
subsystem for low level control.
After successful probe it registers itself as a cooling device for thermal
subsystem.
This driver also supports devices without DTS specified.

With those bindings it is possible to use pwm-fan device available in

Changes for v2:
- Rename cooling-pwm-values property to cooling-levels
Changes for v3:
- Change patch's topic to "ARM dts"
- Reduce maximal cooling-level to 230
This patch provides code for reading PWM FAN configuration data via
device tree. The pwm-fan can work with full speed when configuration
is not provided. However, errors are propagated when wrong DT bindings
are found.
Additionally the struct pwm_fan_ctx has been extended.

Current Exynos CPU idle driver supports entering AFTR (Arm Off, Top
Running) mode on Exynos 4210 (coupled), Exynos 4x12 and Exynos 5250.
Enable it in default configuration to reduce energy consumption.
