I should've known I'd get this response ;-P

During the bisect operation I noticed the following messages:
[    4.920273] ee1004 1-0050: 512 byte EE1004-compliant SPD EEPROM, read-only
[    4.922699] ee1004 1-0051: 512 byte EE1004-compliant SPD EEPROM, read-only
[    4.924960] ee1004 1-0052: 512 byte EE1004-compliant SPD EEPROM, read-only
[    4.927236] ee1004 1-0053: 512 byte EE1004-compliant SPD EEPROM, read-only

but only on some. I didn't get those before, but they're informational
so not a problem. (But I don't care for them either)

``git blame -L '/static int ee1004_probe/' drivers/misc/eeprom/ee1004.c``
showed the ``dev_info`` line has been present since 2018-10-07, but I
guess it never used the ``ee1004_probe`` function before?

Anticipating the likely next question "Can you still reproduce it in
current master/HEAD?" I build a new kernel from this:
075dbe9f6e3c ("Merge tag 'soc-ep93xx-dt-6.12' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc")

And that showed the info messages, but not the error.
So that looks like the bug has been fixed for 6.12.

Cheers,
  Diederik
