Using bcma_debug gives a device-specific prefix for messages and pr_cont
is a common helper for continuing a line.

This isn't the same code as it depends on #define DEBUG
and will not output the first line in most cases.

I'd suggest a nack.

Perhaps it'd be better to use a temporary and avoid the
pr_cont uses like:

{
	int i;
	static const char *irq_name[] = {"2(S)", "3", "4", "5", "6", "D", "I"};
	char interrupts[20];
	char *ints = interrupts;

	for (i = 0; i < ARRAY_SIZE(irq_name), i++)
		ints += sprintf(ints, " %s%c", irq_name[i], i == irq ? '*' : ' ');

	bcma_debug(dev->bus, "core 0x04x, irq: %s\n", dev->id.id, interrupts);
}

Too late, I already applied this. Please submit a followup patch if
something needs to be changed.

Oh, I didn't think about bcma_debug (pr_debug) being no_printk indeed.
AFAIU it will indeed make pr_cont default to the KERN_DEFAULT.

I'll try to test your code today or tomorrow, thanks!
