I disagree.

It does add an always output decimal value to the DPRINT
instead of a mostly mismatched format and argument
	printk(message, marg).

Previous single matched output use of message/marg:

-	reschedule_timeout(MAXTIMEOUT, "request done %d", uptodate);
+	reschedule_timeout(MAXTIMEOUT, "request done", uptodate);

vs now:

$ grep reschedule_timeout drivers/block/floppy.c
static void __reschedule_timeout(int drive, const char *message, int marg)
static void reschedule_timeout(int drive, const char *message, int marg)
	__reschedule_timeout(drive, message, marg);
	__reschedule_timeout(drive, "lock fdc", 0);
	reschedule_timeout(current_reqD, "floppy start", 0);
	reschedule_timeout(MAXTIMEOUT, "do wakeup", 0);
	reschedule_timeout(MAXTIMEOUT, "request done", uptodate);
		reschedule_timeout(current_reqD, "redo fd request", 0);
	reschedule_timeout(MAXTIMEOUT, "floppy init", MAXTIMEOUT);

Arguably, that single use could be something like:

	char msg_buf[sizeof("request done ") + 20];
	snprintf(msg_buf, sizeof(msg_buf), "request_done %d", uptodate);
	reschedule_timeout(MAXTIMEOUT, msg_buf);

(uptodate should be 0, 1 or 2)

with the now unused marg argument removed from
reschedule_timeout and __reschedule_timeout.
