This is the story behind a recent bugzilla. The patches generated on kernel.org only say that the binary files changed so they can’t actually be applied as diffs. Git deals with binary files just fine though so it’s possible to sneak some in and end up with a tree that can’t be easily expressed in patches. Binary files usually don’t have a place in the kernel, but some did come in with a staging driver. The staging driver was deleted this merge window. Everything that isn’t an official x.y kernel release (e.g. 4.3-rc4, 4.2.3) comes in as a patch file so all patches are going to be unappliable until that commit makes it into an official release. The workaround right now is to modify the patch to get rid of the binary file deletion. This does mean the checksums aren’t going to match against kernel.org but this is only going to be the case until the next official release in rawhide which should be sometime at the beginning of January. You’ll just have to trust the Fedora kernel team in the mean time.
