I wanted to let you know that on my Dell XPS-9320, this patchset ended up spamming (i.e., hundreds) my dmesg with the following:

power_supply ucsi-source-psy-USBC000:002: driver reporting unavailable enum value 7

... which I believe to be POWER_SUPPLY_USB_TYPE_PD_DRP .

In my case it was coming from the call to power_supply_show_enum_with_available() on/around line 380 in .../drivers/power/supply/power_supply_sysfs.c ; I'd tried adding POWER_SUPPLY_USB_TYPE_PD_DRP to con->psy_desc.usb_types in ucsi_register_port_psy() in
.../drivers/usb/typec/ucsi/psy.c thinking that may fix it with no success.

LMK if you need any further info,

-Kenny
