Subject: [PATCH] cpufreq: qcom-nvmem: add sentinel to qcom_cpufreq_ipq806x_match_list

From: Pei Xiao <xiaopei01@...inos.cn>

The of_device_id table is expected to be NULL-terminated. Without the
sentinel, the traversal of the array can lead to out-of-bound access,
causing undefined behavior.

This adds the missing sentinel to the qcom_cpufreq_ipq806x_match_list
array.

Fixes: 58f5d39d5ed8 ("cpufreq: qcom-nvmem: add compatible fallback for ipq806x for no SMEM")
