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.
