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

i3c: dw: Fix use-after-free in dw_i3c_master driver due to race condition

In dw_i3c_common_probe, &master->hj_work is bound with
dw_i3c_hj_work. And dw_i3c_master_irq_handler can call
dw_i3c_master_irq_handle_ibis function to start the work.

If we remove the module which will call dw_i3c_common_remove to
make cleanup, it will free master->base through i3c_master_unregister
while the work mentioned above will be used. The sequence of operations
that may lead to a UAF bug is as follows:

CPU0                                      CPU1

                                     | dw_i3c_hj_work
dw_i3c_common_remove                 |
i3c_master_unregister(&master->base) |
device_unregister(&master->dev)      |
device_release                       |
//free master->base                  |
                                     | i3c_master_do_daa(&master->base)
                                     | //use master->base

Fix it by ensuring that the work is canceled before proceeding with
the cleanup in dw_i3c_common_remove.
