The following error occurred when compiling the gpio-button-hotplug module in OpenWRT 18.07
error: implicit declaration of function 'broadcast_uevent'; did you mean 'kobject_uevent'? [-Werror=implicit-function-declaration] broadcast_uevent(event->skb, 0, 1, GFP_KERNEL);
I found that the patch located in the openwrt/target/linux/generic/hack-4.14 was not applied
How to apply these patches on menuconfig?
