CVE-2026-53295

Description

In the Linux kernel, the following vulnerability has been resolved:

mailbox: add sanity check for channel array

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.
