From b535cc796a4b4942cd189652588e8d37c1f5925a Mon Sep 17 00:00:00 2001 From: Steve French Date: Thu, 25 May 2023 18:53:28 -0500 Subject: [PATCH] smb3: missing null check in SMB2_change_notify If plen is null when passed in, we only checked for null in one of the two places where it could be used. Although plen is always valid (not null) for current callers of the SMB2_change_notify function, this change makes it more consistent.
