You can do a 'git format-patch vXXX" where XXX is the latest mainline
tag (like v5.4.12 or something), and see them all that way, or you can
look in the
https://android.googlesource.com/kernel/common-patches repo
which breaks everything out by individual patch and keeps them up to
date in a much easier-to-understand format.
Hope this helps!
