2018.1.1 Magisk v15.2

What is a better way to celebrate 2018 than a Magisk update fixing bugs.This update mainly fixes these main issues:I fixed fstab ramdisk patches in the last release, but forgot to update the dtb part (both uses the same patching logic), my bad. Recently devices are starting to move fstabs from ramdisks into dtbs like OP5/OP5T Oreo beta. Since Magisk's dtb verity removal code is broken in v15.1, this causes devices that triggers dm-verity using the new setup to stuck in a bootloop.Another major update is that new sepolicy rules are added to support stock Samsung ROMs. Samsung users has been complaining MagiskHide broken since the introduction of the refined MagiskHide system, and finally I spent an excessive amount of time and found the root to the issue: SELinux.Lastly, thanks to @ shakalaca joining the forces, there are some devices in the wild using Treble-like split sepolicy setup on a traditional non skip_initramfs devices, this release is updated to support these Frankenstein configurations.Sorry for the frequent updates recently, but I really want things to work out on all devices. Hopefully this will be the last update in this series of v15.X release, finger crossed!For a more complete release note, please check
