Subject: UCSI failing due to probe() getting version 0
Date: Thu, 5 Aug 2021 16:04:03 +0200 [thread overview]
Message-ID: <db9e63df-80cc-6dae-89ae-23cb1cd09425@suse.com> (raw)
Hi,
I am trying this on a new laptop, but I am getting a result I do not
understand.
ucsi_acpi_probe() is called, but ucsi_register() fails with -ENODEV,
because ucsi->version is 0.
If I dump the ucsi_acpi buffer I get:
00 00 00 00 02 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
And, frankly I do not understand that. Why have the ACPI device
but show version number 0?
Regards
Oliver
