Or maybe combine it with the else path:
	slave->mtd.erasesize = master->erasesize;
	if (master->numeraseregions > 1)
		printk(KERN_ERR"mtdpart can not handle multiple eraseregions correctly.\n");

Nemoto-san, would this be good enough for you?  It fixes the bug you
noticed, it removes most long lines and it removes the sparse warning.
It also removes functionality that may have been useful to some person -
detecting a smaller erasesize.  And with some luck and a warm easterly
wind, that functionality may even have worked.
