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, that makes sense.  I tried deleting the if statement and printk()
from ddk750_help.c, and adding the following in lynxfb_pci_probe() after
calling hw_sm750_map() and checking for errors:

if (sm750_dev->revid = 0xfe)
	dev_info(&pdev->dev, "found sm750le\n");

The driver compiles, loads and unloads ok with this code.

Does this look correct?
