      "title": "gpio: tegra: do not call pinctrl for GPIO direction",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\ngpio: tegra: do not call pinctrl for GPIO direction\n\ntegra_gpio_direction_input() and tegra_gpio_direction_output() already\nprogram the GPIO controller direction registers directly. The additional\npinctrl_gpio_direction_input/output() calls do not add a Tegra pinctrl\noperation, because the Tegra pinmux ops provide GPIO request/free\nhandling but no gpio_set_direction hook.\n\nThe extra call still enters the pinctrl core and takes pctldev->mutex.\nShared GPIO users can call the direction path while holding their\nper-line spinlock, so this otherwise redundant pinctrl direction call can\nsleep in an atomic context.\n\nThis was found by our static analysis tool and then confirmed by manual\nreview of tegra_gpio_probe(), the Tegra GPIO direction callbacks and the\nTegra pinctrl ops. The reviewed path has a default non-sleeping\nstruct gpio_chip while the direction callback still enters the pinctrl\nmutex path.\n\nA directed runtime validation kept the same non-sleeping chip registration\nand drove:\n\n  gpio_shared_proxy_direction_output()\n  gpiod_direction_output_raw_commit()\n  tegra_gpio_direction_output()\n  pinctrl_gpio_direction_output()\n\nLockdep reported a sleep-in-atomic warning with the shared GPIO spinlock\nheld and pinctrl_get_device_gpio_range() plus tegra_gpio_direction_output()\non the stack.\n\nDo not mark the whole chip as can_sleep to paper over this: can_sleep\ndescribes whether get()/set() may sleep, and Tegra value access is MMIO.\nRemove the redundant pinctrl direction calls and keep pinctrl involvement\nin the existing request/free path.",
