That's not very true : the "need" is to spare the "manual" kfree you're adding in your patch for one, and make it consistent with pxa2xx_build_groups() and pxa2xx_build_state() for two. Therefore I'm not very thrilled by this patch and unless it fixes a defect in the driver I'd rather not have it in. Cheers. -- Robert
