The upstream commit id *is* called out in the patch, but it's buried
below the three dashes:
The original change was introduced with 6.8, 6.9 added support for
LEDs on RTL8125. Therefore the first version of the fix applied on
6.9-rc only. This is the modified version for 6.8.
Upstream commit: 19fa4f2a85d7
^^^^^^^^^^^^
The proper way to do this is to prominently add ...
commit 19fa4f2a85d777a8052e869c1b892a2f7556569d upstream.
... or ...
[ Upstream commit 19fa4f2a85d777a8052e869c1b892a2f7556569d ]
... as the first line of the commit message, as per
Documentation/process/stable-kernel-rules.rst
