[Fix]
The patch ease the call trace and only shows the firmware bug warning in the log
https://lkml.org/lkml/2025/10/16/154
v3 - https://lore.kernel.org/lkml/20251224070022.4082182-1-acelan.kao@canonical.com/
[Test]
Boot up the machine which shows the same call trace after booted up, the call trace should be replaced by something like this
ucsi_acpi USBC000:00: con0: Firmware bug: duplicate partner altmode SVID 0x8087 at offset 1, ignoring. Please update your system firmware.
[Where problems could occur]
It doesn't affect functionalities, just detect the duplicated modes and skip it.
