Estado: AnalizadaMedia (5.5)—

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

iio: light: isl29028: Fix the warning in isl29028_remove()

The driver use the non-managed form of the register function in isl29028_remove(). To keep the release order as mirroring the ordering in probe, the driver should use non-managed form in probe, too.

The following log reveals it:
