  "description": "In the Linux kernel, the following vulnerability has been resolved:  pinctrl: meson: amlogic-a4: fix deadlock issue  Accessing the pinconf-pins sysfs node may deadlock.  pinconf_pins_show() holds pctldev-\u003Emutex, and the platform driver calls pinctrl_find_gpio_range_from_pin(), which tries to acquire the same mutex again, leading to a deadlock.  Use pinctrl_find_gpio_range_from_pin_nolock() to fix this issue.",
