  "message": "genirq: Make irq_shutdown() symmetric vs. irq_startup again\n\nIf an irq_chip provides .irq_shutdown(), but neither of .irq_disable() or\n.irq_mask(), free_irq() crashes when jumping to NULL.\nFix this by only trying .irq_disable() and .irq_mask() if there\u0027s no\n.irq_shutdown() provided.\n\nThis revives the symmetry with irq_startup(), which tries .irq_startup(),\n.irq_enable(), and irq_unmask(), and makes it consistent with the comment for\nirq_chip.irq_shutdown() in \u003clinux/irq.h\u003e, which says:\n\n * @irq_shutdown:\tshut down the interrupt (defaults to -\u003edisable if NULL)\n\nThis is also how __free_irq() behaved before the big overhaul, cfr. e.g.\n3b56f0585fd4c02d047dc406668cb40159b2d340 (\"genirq: Remove bogus conditional\"),\nwhere the core interrupt code always overrode .irq_shutdown() to\n.irq_disable() if .irq_shutdown() was NULL.\n\nSigned-off-by: Geert Uytterhoeven \u003cgeert@linux-m68k.org\u003e\nCc: linux-m68k@lists.linux-m68k.org\nLink: http://lkml.kernel.org/r/1315742394-16036-2-git-send-email-geert@linux-m68k.org\nCc: stable@kernel.org\nSigned-off-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\n",
