Subject: [PATCH] hwmon: (aspeed-pwm) add THERMAL dependency
Git-commit: d5553c26198f0eea3e6f1d13c51cb548a0a4f260
Patch-mainline: v4.14-rc1
References: bsc#1051510
With CONFIG_THERMAL=m, a built-in aspeed pwm tacho driver causes
a link error:
Drivers/hwmon/aspeed-pwm-tacho.o: In function `aspeed_pwm_tacho_probe':
aspeed-pwm-tacho.c:(.text+0x7f0): undefined reference to `thermal_of_cooling_device_register'
This adds a dependency similar to what other hwmon drivers use,
ensuring that the aspeed driver cannot be built-in in this
case but has to be a module. With THERMAL=n, we still allow building it.
