Why can't you use dev_info() here?

thanks,

It should work, but I'm not sure what should change in the header files to
do it--esp. to make the dev parameter available in ddk750_help.c.  (Only
sm750.c uses dev_ style logging now, the rest of the driver still uses pr_*.)

This printk can be moved to lynxfb_pci_probe, and then it should be no
problem to use dev_info. Just make sure to update the commit message
appropriately. 
 

Thanks,
