[PATCH v3 21/21] staging: r8712u: Most return-values changed from -1 to proper errno macros.

[Greg KH]

In the future, please NEVER put the "v3" in that location in the Subject
line, as I can't sort by the subject to put everything in the correct
order.

Please do:
	[PATCH XX/XX v3]
so I don't have to edit things by hand like I did this time around :(

thanks,

greg k-h
