Subject: [PATCH 08/21] cpufreq: mediatek: Fix NULL pointer dereference in
mediatek-cpufreq
Fix following coccicheck error:
drivers/cpufreq/mediatek-cpufreq.c:464:16-23: ERROR: info is NULL but dereferenced.
Use pr_err instead of dev_err to avoid dereferring a NULL pointer.
Fixes: f52b16ba9fe4 ("cpufreq: mediatek: Use device print to show logs")
