The result of container_of() operations is never NULL unless the embedded
element is the first element of the structure. This is not the case here.
The NULL check on the result of container_of() is therefore unnecessary
and misleading. Remove it.
This change was made automatically with the following Coccinelle script.
@@
type t;
identifier v;
statement s;
@@
<+...
(
t v = container_of(...);
|
v = container_of(...);
)
...
when != v
- if (\( !v \| v == NULL \) ) s
...+>
While at it, remove unused but assigned variable hpd in
dp_display_usbpd_attention_cb().
