[scsi 1/7 RESEND] scsi_debug: define pr_fmt() for consistent logging

[scsi 1/7 RESEND] scsi_debug: define pr_fmt() for consistent logging

[Tomas Winkler]

Use pr_fmt with both module name and __func__
Also drop few bare printk leftovers

The log format should stay pretty much intact

Please refer to the patch I just posted, we can't return _HOST_BUSY here
if devip == NULL.  I posted a fix against the current "misc" branch as
I don't see this patch applied, let me know if I need to update it.

I'm just not sure why the patches are not merged or even rejected.
I'm submitting patches to the Linux kernel for more than 10 years to various trees and  I can agree that these are not some  urgent fixes, but  this is the first time my effort is ignored for such long time by the maintainer. 

Thanks

Because ideally I want a Maintainer ack.  That's Doug Gilbert.

Well, OK, I trust martin, I'll override the lack of Maintainer ack if
you fix as Ewan suggests.

Just to clarify, I didn't have a problem with Tomas' patch per se, it's
just that my patch won't apply on top of his.  I'll submit a v2 if you
want, so you can apply Tomas' patch first.  The problem I'm fixing has
been in there for a while.  Let me know if you want me to do that.

Hopefully your patch should be applied above my patches but I can make that effort and stack them on top of yours.

[scsi 6/7 RESEND] scsi_debug: fix REPORT LUNS Well Known LU

[Tomas Winkler]

The use case to report 'REPORT LUNS WLUN' described
in scsi_debug documentation didn't work because:
scsi_scan_host_selected() checks for:
	 lun < shost->max_lun

To fix this we set:
	max_lun = SCSI_W_LUN_REPORT_LUNS + 1;
