Hi!

5.6-rc0.95 -- based on:

commit fdfa3a6778b194974df77b384cc71eb2e503639a
Merge: 291abfea4746 e0a514259378
Author: Linus Torvalds <torvalds@linux-foundation.org>
Date:   Sat Feb 8 17:24:41 2020 -0800

    Merge tag 'scsi-misc' of
    git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi

/dev/motmdm* is not there for me. Unfortunately,
drivers/mfd/motorola-mdm.c is not mainline, so I can't just try with
the mainline....

Does it work for you?

I have ... rather a lot of warnings in dmesg :-(. /dev/ttyUSB4 works
ok for me.

Can I somehow help get /dev/motmdmX upstream?

Best regards,
								Pavel
