I'm getting panic()s in tpm2_bios_measurements_start()- but don't know why

I'm running Linus' tip as of today, but have seen this in the 5.8.0-18 stock
kernel from Ubuntu.

All of a sudden, after an "apt update", I'd find my laptop (Dell XPS 7390 2-in-1)
randomly rebooted after an OOPS. I've got pstore on, so I found the cause was in
tpm2_bios_measurements_start() (see full dump attached). I guess the "fwupd"
package was what was updated that killed it, as I can reliably stumble upon this
by running "fwupdtpmevlog" (version 1.4.5) even with no arguments.

I've been trying to figure out what the problem was, checking (via printk())
the values for "seq_file" and "pos" for null, or one of the associated pointers
derived from it, and they "printk()" OK, but if I let the code go much further than
the declaration block, it oopses.

I'm now wondering if the "m->private" data being passed is valid. But in any case,
userspace reading a sysfs file (/sys/kernel/security/tpm0/binary_bios_measurements)
shouldn't cause a kernel panic.

Is there anything I can do to help diagnose and fix this?

Thanks,

	-Kenny
