CVE-2025-37910

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

ptp: ocp: Fix NULL dereference in Adva board SMA sysfs operations

On Adva boards, SMA sysfs store/get operations can call _handlesignaloutputs() or _handlesignalinputs() while the irig and dcf pointers are uninitialized, leading to a NULL pointer dereference in _handlesignal() and causing a kernel crash. Adva boards don't use irig or dcf functionality, so add Adva-specific callbacks ptp_ocp_sma_adva_set_outputs() and ptp_ocp_sma_adva_set_inputs() that avoid invoking irig or dcf input/output routines.
