![]() 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. Signed-off-by: Amitoj Kaur Chawla <amitoj1606@gmail.com> Signed-off-by: David S.
