AI-suggested
A fix has been implemented in the Linux kernel to use the _cansleep variant for sleepy GPIOs in the adau1372 driver. Users should update to a patched kernel version that includes this fix to prevent warnings and ensure proper GPIO powerdown behavior.
Description
This vulnerability in the Linux kernel's ASoC adau1372 driver involves improper handling of sleepy powerdown GPIOs. The issue arises because gpiod_set_value() emits a WARN when the GPIO provider indicates it can sleep, which is typical for I2C controlled GPIO expanders. The fix involves using the _cansleep variant to allow the driver to use sleepy GPIOs to power off the chip without warnings.
