I know you guys are working hard. Just wanted to let you know that recently kernel source for Redmi 4A was released. It would be better if someone with deep knowledge in kernel sources could get their hands dirty. https://github.com/MiCode/Xiaomi_Kernel_OpenSource/tree/riva-n-oss.

I love your work. Would like to contribute some day with code.
