This patch indeed doesn't belong into this series. It just happend to be
in my tree and shuffled into the middle when I sorted the patches by
subsystem. Note I already sent it separately at

https://lore.kernel.org/linux-mtd/20240115141245.3415035-2-u.kleine-koenig@pengutronix.de

The problem exists since

3ab8f2a2e701 ("P4080/eLBC: Make Freescale elbc interrupt common to elbc devices")

which was included in v2.6.37-rc1. At that time there was no
EPROBE_DEFER yet. I think I wouldn't add a Fixes: line for that, but
feel free to add one if you think there should be one.

Best regards
Uwe
