CVE-2026-89939

Summary
In the Linux kernel, the following vulnerability has been resolved:
iio: chemical: atlas-sensor: fix PM reference leak in buffer postenable
atlas_buffer_postenable() acquires a runtime PM reference with pm_runtime_resume_and_get() but returns the result of atlas_set_interrupt() directly. If atlas_set_interrupt() fails, the runtime PM reference is leaked and the device can never autosuspend.
Add pm_runtime_put_autosuspend() on the error path to balance the reference.
