Severity
Summary
In the Linux kernel, the following vulnerability has been resolved:
gpio: omap: do not register driver in probe()
Commit 11a78b794496 ("ARM: OMAP: MPUIO wake updates") registers the
omap_mpuio_driver from omap_mpuio_init(), which is called from
omap_gpio_probe().
However, it neither makes sense to register drivers from probe()
callbacks of other drivers, nor does the driver core allow registering
drivers with a device lock already being held.
The latter was revealed by commit dc23806a7c47 ("driver core: enforce
device_lock for driver_match_device()") leading to a potential deadlock
condition described in [1].
Additionally, the omap_mpuio_driver is never unregistered from the
driver core, even if the module is unloaded.
Hence, register the omap_mpuio_driver from the module initcall and
unregister it in module_exit().
