- pinctrl: meson: amlogic-a4: fix deadlock issue
- Details
-
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.
pinconfpinsshow() holds pctldev->mutex, and the platform driver calls pinctrlfindgpiorangefrom_pin(), which tries to acquire the same mutex again, leading to a deadlock.
Use pinctrlfindgpiorangefrompinnolock() to fix this issue.
