hpilo: fix pointer warning in ilo_ccb_setup
Prarit Bhargava [Tue, 10 Aug 2010 00:20:27 +0000 (17:20 -0700)]
Fix i386 PAE compile warning:

drivers/misc/hpilo.c: In function `ilo_ccb_setup':
drivers/misc/hpilo.c:274: warning: cast to pointer from integer of different size

dma_addr_t is 64 on i386 PAE which causes a size mismatch.
