I don't believe the first part of this change is a checkpatch
message.  I think it would be better written by hoisting the
function outside the if like:

	err = cn_add_callback(&cn_proc_event_id, "cn_proc", &cn_proc_mcast_ctl)
	if (err) {
		pr_warn("cn_proc failed to register\n");
		return err;
	}

OK.

Should I submit the whole patch again (with that change) or just
another small patch that does just that?

It's generally better to reply to the original patch
with [PATCH V2] with the entire patch content updated.

btw: there's a missing a semicolon in what I posted.

Also add a changelog after the --- so the new patch
email looks like:

Subject: [PATCH V2] drivers: connectors: etc

Patch description...

Signed-off-by: etc
---
v2: Updated to do whatever

actual patch...

cheers, Joe

[PATCH V2] drivers: connector: fixed coding style issues

[Valentin Ilie]

V2: Replaced assignment in if statement.
Fixed coding style issues.
