Re: [PATCH 0/2] mfd: syscon: introduce no-auto-mmio DT property

[Dan Carpenter]

Yeah.  Let me send this tommorrow if no one objects.  Pretty simple
solution in retrospect.

[PATCH] mfd: syscon: Return -EPROBE_DEFER in device_node_get_regmap()

These days we can register syscons with of_syscon_register_regmap() so
if we can't find the syscon that probably means it hasn't been registered
yet.  Return -EPROBE_DEFER so the driver will try probing again.
