The Beagleboard xM gpio used for TFP410 powerdown is connected through
an I2C attached chip which means setting the GPIO can sleep. Code that
calls tfp410_power_on/off holds a mutex, so sleeping should be fine.

What's the error without this patch? Or just no display?

Just wondering if it's safe to merge Tomi's clean up series to
arm-soc tree..

The only platform that has a problem is Beagleboard xM, and that is
only after 'ARM: OMAP: Cleanup Beagleboard DVI reset gpio' is applied.
Since the context actually can sleep, the only consequence is a
WARN_ON statement.

So yes, it should be safe.

Well since I have not actually merged it with other branches yet, I'll wait
for Tomi to apply that and repull his for-l-o-3.5 branch.
