[PATCH] Revert "scsi: sd: Do not repeat the starting disk message"

[Johan Hovold <johan+linaro@kernel.org>]

This reverts commit 7a6bbc2829d4ab592c7e440a6f6f5deb3cd95db4.

The offending commit tried to suppress a double "Starting disk" message
for some drivers, but instead started spamming the log with bogus
messages every five seconds:

	[  311.798956] sd 0:0:0:0: [sda] Starting disk
	[  316.919103] sd 0:0:0:0: [sda] Starting disk
	[  322.040775] sd 0:0:0:0: [sda] Starting disk
	[  327.161140] sd 0:0:0:0: [sda] Starting disk
	[  332.281352] sd 0:0:0:0: [sda] Starting disk
	[  337.401878] sd 0:0:0:0: [sda] Starting disk
	[  342.521527] sd 0:0:0:0: [sda] Starting disk
	[  345.850401] sd 0:0:0:0: [sda] Starting disk
	[  350.967132] sd 0:0:0:0: [sda] Starting disk
	[  356.090454] sd 0:0:0:0: [sda] Starting disk
	...

on machines that do not actually stop the disk on runtime suspend (e.g.
the Qualcomm sc8280xp CRD with UFS).

Let's just revert for now to address the regression.

Hi,

I just noticed this regression that snuck into 6.10-final and tracked it
down to 7a6bbc2829d4 ("scsi: sd: Do not repeat the starting disk
message").

I wanted to get this out ASAP to address the immediate regression while
someone who cares enough can work out a proper fix for the double start
message (which seems less annoying).

Note that the offending commit is marked for stable.

Johan
