I missed this line when reviewing.
Why are you keeping the function around?
As a result, we now suffer with a build warning:
drivers/mfd/cros_ec_dev.c:265:13: warning: '__remove' defined but not used [-Wunused-function]
static void __remove(struct device *dev) { }
Can I just remove the line? What are the ramifications of doing so?
Please reply swiftly, so resolve this issue in good time.
