This patch is part of a two-patch set, the cover note for which says:
2. Since [1], a "gpio-ranges" property is required in order for pins
to be returned to inputs when freed. Note that without patch 1, the
device never gets out of EPROBE_DEFER.
It looks as though patch 2 has been merged without/before patch 1
("pinctrl: bcm2835: Change init order for gpio hogs").
