AI-suggested

A fix is available in the Linux kernel commits e787fd23d5063c61582c3c27522240b6e6703fde and 6564f394a4a95fad534643a6ca0f1d36ff081799. Users should update to a Linux kernel version including these commits to resolve the issue.

Description

A vulnerability in the Linux kernel's iio frequency driver for adf4377 was fixed by fully initializing the clk_init_data and clk_parent_data structures. Uninitialized members in these structures could cause crashes when certain kernel stack initialization configurations are enabled.
