In fact, I did not find these two commit ids on master or sophgo/for-next.
When testing, I applied this patchset based on the latest sophgo/for-next.
This two id comes from my tree, not the sophgo one. But I
think it should be recognized by the git. For testing, you
can just pick the sophgo/for-next tree and test it.
Don't use commit id from your local git, use public git so other people
can find your base. Generally we use official label, such as 6.11-rc1.
Regards,
Inochi.
