Looks good. I'll prepare a pull request for this one and ask Mauro to get this
fix into 2.6.32-rcX as well since it produces a compiler warning.

I'll also ask Mauro to get the missing drivers/staging/go7007/s2250-loader.h
into 2.6.32-rcX: it apparently fell on the floor when the go7007 driver was
updated in 2.6.32.

Regards,

	Hans
