AI-suggested

A fix is available and has been applied in the Linux kernel after version 4.11. Users should update to a fixed kernel version containing the relevant patches identified by the provided commit hashes to remediate this issue.

Description

A vulnerability in the Linux kernel's ASoC sti driver was fixed by ensuring the IRQ lock is initialized before the IRQ is requested. The issue involved the uni_reader_init() function registering a shared IRQ before initializing the associated lock, which could lead to the interrupt handler being invoked while the lock was uninitialized.
