From af6cc45af3db12f452bfdc9a515da54b56412756 Mon Sep 17 00:00:00 2001 From: Ethan Carter Edwards Date: Mon, 23 Dec 2024 14:41:24 +0000 Subject: [PATCH] cpufreq: sparc: change kzalloc to kcalloc Refactor to use kcalloc instead of kzalloc when multiplying allocation size by count. This refactor prevents unintentional memory overflows. Discovered by checkpatch.pl.
