CVE-2026-53295
Description
In the Linux kernel, the following vulnerability has been resolved:

Fail gracefully if there is no channel array attached to the mailbox controller. Otherwise the later dereference will cause an OOPS which might not be seen because mailbox controllers might instantiate very early. Remove the comment explaining the obvious while here.
