From 4788e613a65df19dbfc481473859c70b23eb5404 Mon Sep 17 00:00:00 2001 From: Kiran Gunda Date: Fri, 28 Jul 2017 12:40:40 +0530 Subject: spmi: pmic-arb: fix memory allocation for mapping_table Allocate the correct memory size (max_pmic_peripherals) for the mapping_table that holds the apid to ppid mapping. Also use a local variable for mapping_table for better alignment of the code.
