Description
In the Linux kernel, the following vulnerability has been resolved:
Input: adp5589-keys - fix NULL pointer dereference
We register a devm action to call adp5589_clear_config() and then pass
the i2c client as argument so that we can call i2c_get_clientdata() in
order to get our device object. However, i2c_set_clientdata() is only
being set at the end of the probe function which means that we'll get a
NULL pointer dereference in case the probe function fails early.
