From d7b6cc199b2dea602b4a2a681cf6d3223a61e2be Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Wed, 9 Jan 2019 13:23:29 +0300 Subject: [PATCH] powerpc/powernv/npu: Allocate enough memory in pnv_try_setup_npu_table_group() There is a typo so we accidentally allocate enough memory for a pointer when we wanted to allocate enough for a struct.
