Or you can fix the real issue! This is what I had to do to fix the
OMAP, all the way down:

078dc5194c0a ARM: omap2: Rewrite WLAN quirk to use GPIO descriptors
94075d16beef ARM: omap2: Get USB hub reset GPIO from descriptor
d5f4fa60d63a ARM/gpio: Push OMAP2 quirk down into TWL4030 driver
c729baa86042 ARM: omap1: Exorcise the legacy GPIO header
df89de979f0e ARM: omap1: Make serial wakeup GPIOs use descriptors
084b6f216778 ARM: omap1: Fix up the Nokia 770 board device IRQs
e519f0bb64ef ARM/mmc: Convert old mmci-omap to GPIO descriptors
767d83361aaa Input: ads7846 - Convert to use software nodes
480c82daa3e4 ARM: omap1: Remove reliance on GPIO numbers from SX1
4c40db6249ff ARM: omap1: Remove reliance on GPIO numbers from PalmTE
fa1ae0cd897b ARM: omap1: Drop header on AMS Delta
c32c81f3dbdf ARM/mfd/gpio: Fixup TPS65010 regression on OMAP1 OSK1
a47137a5134b mfd/omap1: htc-i2cpld: Convert to a pure GPIO driver
6efac0173cd1 ARM: OMAP1: OSK: fix ohci-omap breakage
45c5775460f3 usb: ohci-omap: Fix descriptor conversion
f3ef38160e3d usb: isp1301-omap: Convert to use GPIO descriptors
15d157e87443 usb: ohci-omap: Convert to use GPIO descriptors
e63201f19438 mmc: omap_hsmmc: Delete platform data GPIO CD and WP

And maybe some more. Yeah it's tough, but it can be done!
