These last two should be KERN_CONT
though the block could be rewritten as
if (XGIInitNew(pdev))
printk(KERN_INFO "XGIfb: XGIInitNew() ... OK\n");
else
printk(KERN_ERR "XGIfb: XGIInitNew() ... Fail\n");
Emitting any dmesg output like "XGIInitNew() ... OK\n"
is almost always low value.
Perhaps just emitting on the error case is better:
if (!XGIInitNew(pdev))
printk(KERN_ERR "XGIfb: XBIInitNew() failed\n");
One other thing. It would be better to add
#define pr_fmt(fmt) KBUILD_MODNAME ": " fmt
before any #include and convert all the
printks(KERN_<LEVEL> to pr_<level>(
stripping all the leading XGIfb: too.
