From 5f1e1f42a5a6783280dc155bbe7960a2d039c21b Mon Sep 17 00:00:00 2001 From: Colin Ian King Date: Mon, 4 Jan 2021 12:10:53 +0000 Subject: [PATCH] UPSTREAM: powercap/drivers/dtpm: Fix size of object being allocated The kzalloc allocation for dtpm_cpu is currently allocating the size of the pointer and not the size of the structure. Fix this by using the correct sizeof argument.
