This change has been made with the goal that kernel functions should
return something more descriptive than -1 on failure.
A variable `err` has been introduced for storing error codes.
The return value of kzalloc on failure should return a -1 and not a
-ENOMEM. This was found using Coccinelle. A simplified version of
the semantic patch used is:
//<smpl>
@@
expression *e;
identifier l1;
@@
e = kzalloc(...);
if (e == NULL) {
...
goto l1;
}
l1:
...
return -1
+ -ENOMEM
;
//</smpl
Furthermore, set `err` to -ENOMEM on failure of alloc_netdev(), and to
-ENODEV on failure of register_netdev() and probe_irq_off().
The single call site only checks that the return value is not 0,
hence no change is required at the call site.
