MSI: Simplify BUG() handling in msi_remove_pci_irq_vectors() part 2
Although it might be nice to do a printk before BUG'ing, it's really not necessary, and it complicates the code. The behaviour has changed slightly, in that before we set a flag if the irq had an action, and continued freeing the other irqs. But as I see it that's all irrelevant because we end up BUG'ing anyway. Signed-off-by: Michael Ellerman <michael@ellerman.id.au> Acked-by: Eric W.
