| | | | Pete, Luiz
| | | |
| | | | what about this one?
| | | |
| | | | Actually there is just a check for where is error coming from.
| | | | Maybe that is not the best solution but it allows us to reduce
| | | | the calls to 'printk' :)
| | | |
| | | | P.S. Pete your patch is good but the message about
| | | | worqueue creation fail was to print even if we've
| | | | been faltered on the usb_register procedure.

| | Liuz,
| |
| | but the patch you sent me does call
| |
| | printk(KERN_ERR "%s couldn't create workqueue\n",
ftdi_elan_driver.name);
| |
| | even if error occured in usb_register and that is not good I think.
| | Fix me if I'm wrong.
|
| No, you're right. I missed it.
