**Name of the Vulnerable Software and Affected Versions**
Linux kernel (affected versions not specified)
**Description**
A deadlock issue was introduced in the Linux kernel with commit 39c024b51b560, which improved sync scale mode handling for iio: adis16475. Two deadlocks were introduced: the call to `adis write reg 16()` was not changed to its unlocked version, and the lock was not being released on the success path of the function. This change fixes both issues.
**Recommendations**
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
