Subject: [REGRESSION] Missing bcm5974 touchpad on Macbooks
Date: Mon, 04 Mar 2024 09:35:35 +0100	[thread overview]
Message-ID: <87sf161jjc.wl-tiwai@suse.de> (raw)

Hi,

we've received a few regression reports for openSUSE Leap about the
missing touchpad on Macbooks.  After debugging, this turned out to be
the backport of the commit 2b9c3eb32a699acdd4784d6b93743271b4970899
    Input: bcm5974 - check endpoint type before starting traffic

And, the same regression was confirmed on the upstream 6.8-rc6
kernel.

Reverting the commit above fixes the problem, the touchpad reappears.

The detailed hardware info is found at:
  https://bugzilla.suse.com/show_bug.cgi?id=1220030

Feel free to join the bugzilla above, or let me know if you need
something for debugging, then I'll delegate on the bugzilla.


thanks,

Takashi
