I was checking the Dolby Vision module and noticed a difference in the hashes between the bundled dovi.ko and the latest patched version available.
The one currently included in /flash/dovi.ko outputs this SHA-256 hash: c3f0189c01499e9d965bb81177c9348d5ee40845336de27fa9c1dd4f21f4ebbb
the latest 5.15_2.6_dovi_patched_fix_fel.ko https://discourse.coreelec.org/t/fel-amlogic-no-support/58631 has a different hash: f6c26659a255447685ceac9441e399c999b1fae9c6435c48d70e14a14dd7f8f7
