powerpc: Fix irq_free_virt by adjusting bounds before loop
Instead of looping over each irq and checking against the irq array bounds, adjust the bounds before looping. The old code will not free any irq if the irq + count is above irq_virq_count because the test in the loop is testing irq + count instead of irq + i. This code checks the limits to avoid unsigned integer overflows. Signed-off-by: Milton Miller <miltonm@bga.com> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
