Hi,

I tested 3.10-rc1 on OMAP1 / Nokia 770, and Retu MFD probe is broken:

[    2.264221] retu-mfd 2-0001: Retu v3.2 found
[    2.281951] retu-mfd 2-0001: Failed to allocate IRQs: -12
[    2.300140] retu-mfd: probe of 2-0001 failed with error -12

The error is coming from regmap code. According to git bisect, it is
caused by:

	commit ede4d7a5b9835510fd1f724367f68d2fa4128453
	Author: Jon Hunter <jon-hunter@ti.com>
	Date:   Fri Mar 1 11:22:47 2013 -0600

	    gpio/omap: convert gpio irq domain to linear mapping

The commit does not anymore revert cleanly, and I haven't yet tried
crafting a manual revert, so any fix proposals/ideas are welcome...

Thanks,

A.
