Hi, guys:
I am reading function scull_init_module() in scull driver.I found that
scull_init_module() doesn't check scull_setup_cdev()'s return value.If
there will be a probem when scull_setup_cdev() failed, and then, others
call scull_cleanup_module()?
for (i = 0; i < scull_nr_devs; i++) {
scull_devices[i].quantum = scull_quantum;
scull_devices[i].qset = scull_qset;
init_MUTEX(&scull_devices[i].sem);
scull_setup_cdev(&scull_devices[i], i);
}
Best Regard
----
