What to do
AI-suggested
A fix has been applied in the Linux kernel to allow GPIOs to sleep in the nxp-nci NFC driver, resolving the kernel warning and improving driver operation. Users should update to the fixed kernel version once available.
Description
A vulnerability in the Linux kernel NFC driver (nxp-nci) was resolved by allowing GPIOs to enter sleep mode. This fix addresses a kernel warning (WARN_ON) related to GPIO operations, enabling the driver to properly handle GPIOs connected via I2C GPIO expanders.
