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

ptp: ocp: Limit signal/freq counts in summary output functions

The debugfs summary output could access uninitialized elements in
the freq_in[] and signal_out[] arrays, causing NULL pointer
dereferences and triggering a kernel Oops (page_fault_oops).
This patch adds u8 fields (nr_freq_in, nr_signal_out) to track the
number of initialized elements, with a maximum of 4 per array.
The summary output functions are updated to respect these limits,
preventing out-of-bounds access and ensuring safe array handling.

Widen the label variables because the change confuses GCC about
max length of the strings.
