CVE-2026-46205

Description

In the Linux kernel, the following vulnerability has been resolved: staging: media: atomisp: Disallow all private IOCTLs Disallow all private IOCTLs. These aren't quite as safe as one could assume of IOCTL handlers; disable them for now. Instead of removing the code, return in the beginning of the function if cmd is non-zero in order to keep static checkers happy.
