Doc Text:
A flaw was found in the Linux kernel's `gp2ap002` light sensor driver. When the driver attempts to read lux values and encounters an error, it fails to properly release a power management resource. This oversight leads to a permanent leak of the resource, which prevents the affected device from automatically entering a low-power state (autosuspending). The primary impact is increased power consumption for devices utilizing this driver.

Description OSIDB Bzimport 2026-07-25 10:10:56 UTC 
In the Linux kernel, the following vulnerability has been resolved:

iio: light: gp2ap002: fix runtime PM leak on read error

gp2ap002_read_raw() calls pm_runtime_get_sync() before reading the
lux value, but if gp2ap002_get_lux() fails, it returns directly. This
skips the pm_runtime_put_autosuspend() call at the "out" label,
permanently leaking a runtime PM reference and preventing the device
from autosuspending.

Replace the direct return with a "goto out" to ensure the reference
is properly dropped on the error path.
