      "title": "gpio: ml-ioh: use raw_spinlock_t for the register lock",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\ngpio: ml-ioh: use raw_spinlock_t for the register lock\n\nioh_irq_type() is registered as the irq_chip .irq_set_type callback and\ntakes chip->spinlock with spin_lock_irqsave().  This callback is reached\nfrom __setup_irq() -> __irq_set_trigger() -> chip->irq_set_type() while\nthe caller holds desc->lock, a raw_spinlock_t, with hardirqs disabled.\nThat context is not sleepable, but on PREEMPT_RT a regular spinlock_t is\nan rtmutex-backed sleeping lock, so acquiring it there is invalid.\nioh_irq_enable() and ioh_irq_disable() take the same lock from the\n.irq_enable/.irq_disable callbacks, which are likewise invoked with\ndesc->lock held.\n\nConvert the register lock to raw_spinlock_t.  The same lock also\nserializes the GPIO direction/value callbacks and the suspend/resume\nregister save/restore, and those critical sections only perform short\nsequences of MMIO register accesses (ioread32()/iowrite32()); the\n.irq_set_type callback additionally emits a dev_warn() on an unsupported\ntype.  None of these are sleepable operations, so keeping this register\nlock non-sleeping is appropriate for the irqchip callbacks and does not\nchange the GPIO-side locking contract.\n\nThis is the same fix as commit a02b8950d619 (\"gpio: pch: use\nraw_spinlock_t for the register lock\"); this driver shares the same\nstructure as gpio-pch.",
