CVE-2026-98657

In the Linux kernel, the following vulnerability has been resolved:

iio: proximity: pulsedlight: fix iio device left registered on PM setup failure

pm runtime set active() failing in probe() jumps to error unreg buffer, which only calls iio triggered buffer cleanup() -- it does not undo the iio device register() that already succeeded a few lines above. probe() then returns the error, the devm-managed indio dev is freed, but the iio core still has it registered: the sysfs/chardev nodes stay live and point at freed memory.

Add an error unreg dev label that unregisters the iio device before falling through to the existing buffer cleanup, mirroring the teardown order already used in lidar remove().
