Hi.

I noticed the linux-rp-2.6.23 on angstrom (MACHINE=hx2000) doesn't
compile on stable/2009 because of errors in the hx2750 code (probably
was not updated).

The attached patch makes it compile again. Not tested yet, might not
have full pm functionality (if it ever had).

Cheers,
Johannes

Subject: [PATCH] made hx2750 compile again

note that the hx2750_pm_ops struct now is quite crippled, I don't really
know where all the functionality went.
