Description
Description
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.
