What to do

AI-suggested

A fix has been implemented in the Linux kernel to address this issue by ensuring the runtime PM reference is properly released on error paths. Users should update to the fixed kernel version once available to resolve this leak. No additional mitigation actions are indicated.

Description

A runtime power management (PM) reference leak was identified and fixed in the Linux kernel's mpl115 pressure sensor driver. The function mpl115_read_raw() failed to release a PM reference on read errors, causing the device to remain active and preventing autosuspend. The fix ensures that the PM reference is dropped on both success and error paths, preventing resource leaks.
