    CVE-2026-89934

    In the Linux kernel, the following vulnerability has been resolved: iio: light: ltrf216a: fix runtime PM reference leak in error path ltrf216a_get_lux() acquires a runtime PM reference by calling ltrf216a_set_power_state(data, true). However, if ltrf216a_read_data() fails, the function returns immediately without dropping the reference. This leaves the runtime PM usage count unbalanced, preventing the device from autosuspending after a failed read. Fix this by releasing the runtime PM reference before returning from the error path.
