In the Linux kernel, the following vulnerability has been resolved: iio: pressure: mpl115: fix runtime PM leak on read error mpl115_read_raw() takes a runtime PM reference with pm_runtime_get_sync() before reading the processed pressure or raw temperature, but on the read error path it returns without calling pm_runtime_put_autosuspend(). Each failed read therefore leaks a runtime PM reference and prevents the device from autosuspending. Drop the reference before checking the return value so both the success and error paths are balanced.

A flaw was found in the Linux kernel's `mpl115` pressure sensor driver. When a read error occurs in the `mpl115_read_raw()` function, the driver fails to properly release a Power Management (PM) reference. This oversight leads to a continuous leak of PM references with each failed read. The accumulation of these unreleased references can prevent the affected device from entering an autosuspend state, potentially leading to increased power consumption or other resource management issues.
