Add device number to all ubi layer message types.

Adding "error" and "warning" to the message logs is
duplicative to the KERN_<LEVEL> logging information.

Changes from V5:
	- Added ptr verification @ ubi_err/ubi_msg/ubi_warn
	Removed extra printing of ubi number
	Removed new messages.

Did you all ever look at what I posted?

I did. Its not my place to re-post your change in my patch. I personally prefer it the way I've done it but it's just a matter of opinion and personal preference. Artem took this one in...


https://lkml.org/lkml/2014/10/14/280

smaller code, consistent prefixing, consistent with
typical kernel style, etc.

While testing I noticed that the log output looks quite different.

e.g.
[   26.564111] UBI-0: ubi_attach_mtd_dev:default fastmap pool size: 256
[   26.565438] UBI-0: ubi_attach_mtd_dev:default fastmap WL pool size: 128

If __func__ is really desired, it's generally better to
put a space after the "%s:", __func__ so there's visual
separation between the prefixes and the content.

I agree that emitting function names isn't particularly
useful.

I have to disagree here, but again - this is personal preference.


(and Richard, do please remember to trim your posts,
  you sent > 100KB of unnecessary quoted stuff)



Thanks,
Tanya Brokhman
