It's time to remove it from keymap now, I have done some job in the
video_output subdriver for this event ;)

okay, will split the hwmon driver out and send it to lm-sensors mailing
list.

Yes, a switch for turning off/on the backlight, seems no need to report
this key to the users, will remove it too.

get it, thanks!
I have checked the return value in the module init function:
[...]
yeeloong_init()
{
[...]
ret = yeeloong_hotkey_init(&yeeloong_pdev->dev);
if (ret) {
yeeloong_hotkey_exit();
printk(KERN_INFO "Fail init yeeloong hotkey driver.\n");
return ret;
}
[...]
}
[...]
static void yeeloong_hotkey_exit(void)
{
/* free irq */
remove_irq(SCI_IRQ_NUM, &sci_irqaction);
...
}
but as a standalone driver, It's better to do something as following:
if (!yeeloong_hotkey_dev) {
yeeloong_hotkey_exit();
return -ENOMEM;
}
Thanks & Regards!
