This is a code snippet from line 63 of drivers: pnp: isapnp: proc.c This is an error I came across while looking through some checkpatch errors.
if (!(de = bus->procdir)) {
sprintf(name, "%02x", bus->number);
de = bus->procdir = proc_mkdir(name, isapnp_proc_bus_dir);
if (!de)
return -ENOMEM;
}
In the above code snippet is assignment inside the if statement
necessary? Can the assignment be done outside the if statement as it is
a good coding style practice?
Is that change sufficient? I dont want to just shut checkpatch errors as I
really want to improve the code.
Thankyou for taking your time to go through this.
