LPFC compilation error in 2.6.24-git12/git13

[Wenji Huang]

Hi,

 Found compilation error in 2.6.24-git12/git13:

  CC [M]  drivers/scsi/lpfc/lpfc_mem.o
  CC [M]  drivers/scsi/lpfc/lpfc_sli.o

drivers/scsi/lpfc/lpfc_init.c: In function ‘lpfc_pci_probe_one':
drivers/scsi/lpfc/lpfc_init.c:1897: error: implicit declaration of 
function ‘pci_enable_device_bars'

make[2]: *** [drivers/scsi/lpfc] Error 2

pci_enable_device_bars is removed in commit 
215e871aaa3d94540121a3809d80d0c5e5686e4f.

Following suggestions from:

http://lkml.org/lkml/2007/12/17/422
and
http://www.gossamer-threads.com/lists/linux/kernel/873333

This is my suggested patch:

        if (pci_request_selected_regions(pdev, bars, LPFC_DRIVER_NAME))
                goto out_disable_device;

Is that correct?

Sorry got my order wrong :-):

As already discussed and pointed out on LKML and linux-scsi, this is the 
wrong change.  Look at the line above the one you changed -- we want mem 
not io.
