x86: Readd missing irq_to_desc() in fixup_irq()
commit a3c08e5d(x86: Convert irq_chip access to new functions) accidentally zapped desc = irq_to_desc(irq); in the vector loop. So we lock some random irq descriptor. Add it back. Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Cc: <stable@kernel.org> # .37
