From 4a30dcac38c2b34f5b4f358630774bc2c2c104b0 Mon Sep 17 00:00:00 2001 From: Neil Armstrong Date: Fri, 23 Feb 2024 10:40:40 +0100 Subject: usb: typec: ucsi: fix UCSI on SM8550 & SM8650 Qualcomm devices On SM8550 and SM8650 Qualcomm platforms a call to UCSI_GET_PDOS for non-PD partners will cause a firmware crash with no easy way to recover from it. Add UCSI_NO_PARTNER_PDOS quirk for those platform until we find a way to properly handle the crash.
